The Simple Production Process of Underwear

A Complete Guide from Material Selection to Finished Product Underwear is an essential piece of intimate clothing in our daily lives. It not only provides comfort but also protects the hygiene of private parts. Although there are various brands and styles of underwear available on the market, making it by yourself can better meet individual needs, such as adjusting the size, choosing your favorite fabric, or even designing a unique style. This article will introduce the simple production process of underwear in detail to help beginners get started easily.

I. Preparation Before Production 

1. Select Appropriate Materials

The fabric of underwear directly affects the wearing comfort, so material selection is very important. Common underwear fabrics include:  

• Cotton fabric: It is breathable and sweat-absorbent, suitable for daily wear.

• Modal: It is soft and skin-friendly with good elasticity, suitable for those who pursue comfort.

• Lycra or spandex: It enhances elasticity and is suitable for sporty underwear.

• Silk or lace: It is suitable for making sexy or underwear for special occasions.

 2. Prepare Tools  

• Sewing machine (or hand-sewing needle and thread)

• Scissors

• Ruler, tailor's chalk or water-soluble pen

• Elastic band (used for the waist and leg openings)

• Sewing kit (for backup)  

3. Measure Sizes

Before making underwear, you need to accurately measure the following body data:  

• Waist circumference (determines the length of the waist elastic band)

• Hip circumference (determines the width of the pant body)

• Thigh circumference (determines the tightness of the pant legs)  

II. Production Steps of Underwear

1. Draw the Pattern

The pattern is the basis for making underwear and can be drawn in the following way:  • Triangular panties: Draw an isosceles triangle. Adjust the width of the base according to the hip circumference and the height according to personal preference. • Boxer briefs: It is similar to the cutting of shorts, and the pant legs are relatively loose. • Thong: The back piece is relatively narrow, suitable for special needs.  

2. Cut the Fabric

Place the pattern on the selected fabric, trace the outline with tailor's chalk or a water-soluble pen, and then cut it with scissors. Usually, you need:

• Front piece ×1

• Back piece ×1

• Gusset (optional, to increase comfort)  

3. Sew Each Part

Step 1: Sew the front and back pieces

Align the side edges of the front and back pieces and fix them with a sewing machine or by hand-sewing.

Step 2: Install the gusset (optional)

If you choose to add a gusset, sew a rectangular fabric to the key part of the pants to enhance moisture absorption and comfort.

Step 3: Deal with the waist elastic band

Measure the length of the waist elastic band (usually 10%-20% shorter than the actual waist circumference to ensure a snug fit).

Fix the elastic band to the edge of the fabric at the waist and sew it with a zigzag stitch.

Step 4: Deal with the leg elastic band (for boxer briefs)

If making boxer briefs, add an elastic band to the pant leg part in the same way as the waist.

4. Edge Finishing and Detail Treatment

Use binding tape or an overlocker to process all the edges to prevent the fabric from fraying.

Check for any loose threads and trim them clean.

Try it on and adjust it to ensure that the underwear fits comfortably.  

III. Adjustment Techniques for Different Styles 

1.Variations of Women's Panties  

• High-waist style: Increase the height of the waist to provide better abdominal support.

• Low-waist style: Reduce the height of the waist, suitable for matching with low-rise pants.

• Lace decoration: Add lace to the edges to increase the aesthetic appeal.  

2. Key Points for Making Men's Underwear  

• Loose fit: Men's underwear usually requires more room for movement, so you can appropriately increase the width of the pant legs.

• Strengthen the gusset: Use double-layered cotton fabric or breathable mesh fabric to improve comfort.  

IV. Common Problems and Solutions

1. The elastic band is too tight or too loose

If it is too tight, you can replace it with a wider elastic band or increase its length.

If it is too loose, you can remove it and sew a shorter elastic band.

2. The fabric pills or deforms

Choose high-quality fabrics and avoid cheap chemical fiber materials.

Use the gentle mode when washing and avoid excessive pulling during machine washing.

3. The stitches are not firm

Use elastic thread or special underwear sewing thread.

Check the tension setting of the sewing machine to ensure even stitches.  

V. Environmental Protection and Personalization Suggestions

1. Transform old clothes

You can transform old T-shirts or bed sheets into underwear, which is both environmentally friendly and economical.

2. Personalized printing or embroidery

Add your favorite patterns or letters to the underwear to create a unique design.  

Conclusion: Making underwear is not complicated. As long as you master the basic steps, you can easily complete it. Whether it is to save money, pursue personalization, or simply enjoy the fun of handicrafts, making your own underwear is a good choice.
