If you want to turn your fashion design sketches into reality, you’ll need to create a fashion tech pack. A tech pack is a document that contains all the information a factory needs to know in order to manufacture your design. This includes things like measurements, materials, construction details, and more. Creating a tech pack may seem like a daunting task, but it’s actually not that difficult once you know what to include. Here’s a step-by-step guide to help you get started.

What is a Fashion Tech Pack?

A fashion tech pack (also known as a garment spec or spec sheet) is a document used by apparel manufacturing companies to communicate specific garment details to their suppliers. This includes instructions on fabric, trims, construction, and sizing. A fashion tech pack contains all the information a factory needs to know to produce a garment. A well-made tech pack will save you time and money by reducing the need for sample changes and preventing mistakes in production.

Design sketch

A fashion design sketch is a fashion designer’s drawing of a garment. They are often done by hand, using pen and ink, watercolor, or markers. They can also be done digitally with graphic design software. A sketch can be used to communicate the designer’s idea to others who will be involved in creating the garment, such as pattern-makers, sample-makers, and manufacturers. A sketch can also be used as the basis for a fashion illustration.

Technical drawing

A fashion sketch (technically called a “flat”) is a sketch of a garment as seen from one side. The sketch usually shows the garment as if it has been draped on a dress form. Most fashion flats are drawn with a colored pencil or marker on tracing paper; however, some flats are produced by computer software.

Fashion tech pack is an industry name for a set of documents that contain all the information needed to develop, manufacture, and produce a clothing product. A fashion tech pack typically includes sketches or illustrations of the garments, as well as technical specifications such as measurements, fabric and trim details, construction details, etc.

Bill of materials

A bill of materials is a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, components, parts and the quantities of each needed to manufacture an end product. The bill of materials is often used in conjunction with a process flow chart.

The bill of materials is used by production planners to generate production schedules and purchase requisitions. It is also sometimes used by sales and marketing departments as a way to communicate product features and customer benefits to potential buyers. In recent years, the bill of materials has become increasingly important as more companies adopt lean manufacturing philosophies and principles.

Construction details

Construction details and specifications are critical to turning your design vision into a reality. A comprehensive tech pack will contain all the information a manufacturer needs to produce your garments, including measurements, materials, construction details, trim details, and packaging requirements. Creating an accurate and complete tech pack is essential to achieving a successful final product.

There are many different ways to format a tech pack, but most will include the following elements:

-A detailed sketch of the garment with all measurements listed
-A description of the materials and trim to be used
-Construction details such as stitching, hemming, etc.
-Packaging requirements such as hangtags, labels, etc.

Creating a tech pack may seem like a daunting task, but there are many resources available to help you get started. Once you have created your first tech pack, you will be able to reuse many of the same elements for future designs.


There are a few key measurements that you will need to include in your fashion tech pack in order for your manufacturer to create the garment correctly. These measurements include:

-Inseam (for pants)
-Sleeve Length (for tops and dresses)
-Shoulder Width (for tops and dresses)

You will also need to include any special instructions for measurements, such as “Measure from shoulder seam to hem” or “Measure around the fullest part of the bust/chest.” Be as specific as possible so that there is no confusion when the garment is being made.

How to Make a Fashion Tech Pack

A fashion tech pack, also known as a technical package, is a document containing all the critical information needed to develop a garment. This document includes detailed sketches, specifications, measurements, fabric details, trims, and any other special instructions. A tech pack is essential for clear communication between the designer and the manufacturer. In this article, we’ll show you how to make a fashion tech pack.

Choose your software

There are many software programs available to create a tech pack. Some are fashion specific, while others are general design programs. Decide which is best for you based on your needs and skill level. If you are just starting out, look for a program that is easy to use and has a wide range of features. If you are more experienced, you may want a program that is specific to fashion and allows you to create more complex designs.

Fashion software programs:
– Adobe Illustrator
– FashionCAD
– Techpacker
– Optitex
– Pattern maker
– Clo3D

General design programs:
– Photoshop
– Inkscape

Create your sketch

The first step in making your fashion tech pack is to create a sketch of your design. This can be done by hand or on the computer. If you are creating your sketch by hand, be sure to use light lines so that you can erase them later if needed. When you are sketching on the computer, you can use a program like Adobe Illustrator or Photoshop. Once you have created your sketch, you will need to scan it or take a picture of it so that you can upload it into your fashion tech pack template later.

Create your technical drawing

Most designers will create a hand sketch of their fashion design idea. This sketch is then used to create a digital sketch, or illustration, of the design. The illustration is used to generate a technical drawing, which provides all the measurements and construction details necessary to produce the garment.

Creating a technical drawing may seem daunting, but it’s actually quite simple. Begin by opening up a new file in your preferred vector editing software. We recommend using Adobe Illustrator.

Once you have your blank file open, you’ll want to start by sketching out the general shape of your garment. This doesn’t have to be perfect, but it should be reasonably close to the final design. Once you have the general shape sketched out, you can begin fleshing out the details.

Start by adding in all of the seams and darts that will be required to construct the garment. Be sure to include both front and back views in your drawing. Once all of the seams are in place, you can add in pockets, waistbands, collar details, etc.

Once all of the construction details are in place, you’ll want to add in any special markings that will be needed for production. This could include logo placements, color blocks, trim details, etc. All of these markings should be clearly called out with appropriate annotations.

Once your technical drawing is complete, it’s time to start generating your tech pack!

Add your bill of materials

A bill of materials (BOM) is an essential part of any fashion tech pack. It’s a complete list of all the materials, trims, and components that are required to make your garment.

Creating a comprehensive BOM can be time-consuming, but it’s worth taking the time to do it right. A well-made BOM ensures that your manufacturer understands exactly what you want and prevents costly mistakes.

Here’s what you need to know about creating a BOM for your fashion tech pack:

###1. Include all materials, trims, and components
When making your BOM, be sure to include everything that’s required to make your garment. This includes all fabrics, lining materials, zippers, buttons, snaps, hook-and-eye closures, threads, elastic bands, interfacing materials, and so on.

For each material, trim, or component on your BOM, be sure to include the following information:

**Description:** A brief description of the item. For example: “Navy blue polyester fabric.”

**Supplier:** The name and contact information for the supplier of the item. For example: “John Smith Co., [email protected].”

**Quantity:** The amount of the item that is needed to make the garment. For example: “3 yards.”

###2. specify sizes and colors for each component
If your garment comes in multiple sizes or colors, be sure to specify which size or color is required for each component on your BOM. For example: “2 yards of navy blue fabric for size Small” or “1 zipper in Black.”

This is especially important if you’re working with multiple suppliers; you don’t want one supplier sending you zippers in red while another sends you zippers in black!

If your garment comes in multiple sizes or colors but each size or color uses the same components (for example, they all use the same black zipper), then you can simply list the quantities needed for each size or color variation on your BOM rather than listing each component separately. For example: “4 yards of navy blue fabric for size Small,” “5 yards of navy blue fabric for size Medium,” etc.

###3. Group related items together Sometimes it can be helpful to group related items together on your BOM. For example, if you have a garment with multiple pockets, you could create a separate “pocket” section on your BOM and list all of the pocket components together rather than scattered throughout the other sections of your BOM.

This can help make your tech pack more organized and easier to read; just be sure not to group items together so they’re no longer logically grouped with other similar items (for example, don’t put snaps in with buttons just because they’re both fasteners!).

###4. Indicate where each component goes It’s also important to indicate where each component goes on your garment so there’s no confusion during production. For example: “2 yards of navy blue fabric for size Small – body” or “1 zipper in Black – center back seam.”

This ensures that all components end up in the right place on your garment when it’s being made!

Creating a complete and accurate bill of materials is an essential part of any fashion tech pack. By including all materials, trims, and components on your BOM and specifying sizes and colors as necessary, you can help prevent costly mistakes during production

Add construction details

Construction details are critical for any garment. They provide the skeleton or road map for the garment, and ensure that it can be reproduced consistently time after time. A good construction detail should be easy to understand, accurate, and complete. Here are some tips on how to create construction details that will meet all of these criteria:

-Start by sketching out the garment. This will give you a good overview of all of the parts that need to be included in the tech pack.
-Label each part of the garment on the sketch. This will make it easier to identify each part when you start creating the tech pack.
-Take measurements of the garment. Be sure to include all critical measurements, such as chest, waist, hip, sleeve length, etc.
-Create a detailed sketch of each individual part of the garment. Include all seams, darts, pleats, etc.
-Indicate on each sketch how the different parts of the garment should be assembled. This will make it easier for the manufacturer to understand how the garment should be constructed.
-Make sure that all sketches are to scale and include accurate measurements. This will ensure that the finished garment will fit properly and meet your expectations.

Add measurements

Until now, you have learned about the basics of a tech pack and what information is essential in order to create one. In this section, we will go over how to add measurements to your tech pack in order to provide your factory with specific instructions on how to construct your garments.

There are two main ways that you can add measurements to your tech pack- either by listing the measurements out or by providing a detailed sketch.

If you choose to list the measurements out, it is important to be as specific as possible in order to avoid any confusion. Be sure to include all relevant information such as the measurement name, unit of measurement, and where on the garment the measurement should be taken from. It is also helpful to include a clear description of how the measurement should be taken in order to ensure that it is consistent across all garments.

If you choose to provide a detailed sketch of the garment, it is important to include all relevant information such as the measurement name, unit of measurement, and where on the garment the measurement should be taken from. In addition, it is helpful to include an arrow or some other indicator on the sketch itself so that there is no confusion about which way the garment should be facing when taking the measurements. As with listing out measurements, it is also helpful to include a clear description of how the measurement should be taken in order to ensure consistency across all garments.

Whichever method you choose, it is important that you are as clear and concise as possible in order not to cause any confusion for your factory. By taking the time to fill out your tech pack thoroughly and accurately, you will save yourself time and money in the long run by avoiding potential errors in production.


Fashion tech packs are an essential tool for any fashion designer. They help you communicate your design ideas to manufacturers, and they ensure that your garments are made to your specifications. Creating a fashion tech pack is not difficult, but it does require some knowledge of Adobe Illustrator or another vector graphics program.

Once you have created your fashion tech pack, you can use it to solicit quotes from manufacturers, request samples, and track your garment production.
