DIY Panties: Sew Your Own Comfortable Everyday Underwear

 

Sew your own comfortable panties without a pattern using soft knit or tricot fabric, elastic, and a pair you already own for a perfect custom fit.

How to Sew Comfortable, Custom-Fit Underwear Without a Pattern Using a Pair You Already Own

Dear Readers and Subscribers,

There’s something incredibly satisfying about sewing your own basics—and yes, that includes panties. But here’s the best part: you don’t need a sewing pattern to do it.

If you already have a pair of panties that fit you well—even if they’re worn out—you already have everything you need. Instead of adjusting a commercial pattern, you can simply trace what already works for your body and recreate it in fabrics and colors you love.

This method will give you a custom fit, better comfort, and complete control over your materials.

What Kind of Elastic Should You Use for Panties?

Choosing the right elastic is just as important as choosing the fabric. The wrong elastic can make your panties uncomfortable, while the right one makes them feel like your favorite pair from the very first wear.

Knit Elastic (Best for Beginners)

Soft and comfortable

Does not narrow when stretched

Easy to sew

Best for everyday panties

Lingerie Elastic (Picot Elastic)

Lightweight and flexible

Decorative edge

Professional finish

Fold-Over Elastic (FOE)

Folds over raw edges

Clean, modern finish

Great for quick sewing

Elastic Width Guide

Waist: ½" to 1"

Leg openings: ¼" to ½"

Avoid These

Heavy or stiff elastic

Braided elastic (can twist)

How Much Elastic to Use

The Elastic should be slightly smaller than the opening so it hugs the body comfortably.

Use 85%–90% of the opening measurement

Example:

30" waist → 25.5"–27" elastic

20" leg → 17"–18" elastic

How to Add Elastic

Step 1: Divide Into Quarters

Step 2: Pin Elastic to Fabric

Step 3: Sew While Stretching Elastic

Stretch the elastic—not the fabric.

Step 4: Fold and Topstitch

Helpful Tips

Use a ballpoint needle

Use zigzag stitch

Test on scrap fabric

Adjust the elastic for comfort

Make Them Your Own

Add lace

Use contrast elastic

Sew matching sets

Batch sew multiple pairs
