How to Make Incontinence Underwear for Women | DIY Sewing Tips

The DIY route works best for light, stress-related leaks, and it lets you control the absorbency placement and the fit. If the goal is saving money or customizing coverage, a homemade pair can do the job. For moderate to heavy leakage, ready-made protective underwear is usually the more reliable option, and knowing when to switch matters just as much as knowing how to sew.

Understanding the Three-Layer System

Every successful homemade pair relies on the same core construction concept: a gusset built from three functional layers. The layer against the skin wicks moisture away, the middle layer absorbs it, and the outer layer keeps it from reaching your clothes.

• Wicking layer: a soft knit that pulls urine away from the skin, such as bamboo or synthetic athletic mesh.
• Absorbent core: one to four layers of cotton fleece, hemp, or a specialty absorbent fabric like Zorb. For stress incontinence—leaks from coughing, sneezing, or exercise—concentrate these layers toward the front and center of the gusset.
• Waterproof barrier: a TPU or PUL laminate on the outside that stops moisture from passing through to your pants.

Baste the layers together first, then sew the assembled gusset into the underwear body. Start with a pattern that already fits well, or trace a favorite pair you own to get the rise and leg openings right.

Sewing Techniques That Prevent Leaks

The sewing details decide whether your underwear actually holds liquid. Use a ballpoint or stretch needle in size 70/10 or 80/12 so the knit fabrics feed cleanly. Set your stitch length to 3 mm or longer, because dense stitching creates holes that defeat the waterproof layer.

Go slow over the TPU or PUL barrier, and avoid backstitching in the same spot multiple times. A Teflon or walking foot helps the slippery waterproof fabric move without sticking. After stitching, you can apply seam-sealing tape or a waterproofing spray to the stitched areas of the barrier side to close any needle perforations.

One of the most common mistakes is choosing the wrong size. The gusset can only do its job if the underwear sits snugly against the body, and a poor fit also causes skin soreness from friction. Measure your waist, hips, and legs, and compare them to the pattern’s finished measurements before you cut.

Care Instructions That Extend the Life

Homemade incontinence underwear needs specific washing to keep the layers working and the skin healthy. Rinse the garment in cold water first to flush out urine, then wash at the warmest temperature the fabric label allows. Use a mild detergent and run the rinse cycle twice.

Avoid bleach and fabric softener completely. Bleach breaks down the absorbent fibers, and softener coats them with a residue that repels liquid instead of soaking it up. Air drying is gentler on the waterproof membrane than a hot dryer.

Prompt changing is non-negotiable for skin health. Change as soon as you feel a leak, wash your hands before and after, and clean and dry the skin thoroughly. A barrier cream can help if skin stays exposed to moisture throughout the day.

When Ready-Made Options Fit Better

DIY construction suits light leakage, but official guidance groups commercial protective underwear under moderate to heavy incontinence. When leakage is heavier or the cause is unclear, store-bought options simply absorb more, faster.

The National Association for Continence lists washable incontinence underwear, protective underwear, pads and liners, waterproof pants, pessaries, and urethral inserts as available US product categories. Brands like Poise, Depend, Knix, and TENA all make women’s washable incontinence underwear, and retail claims emphasize absorbency, odor control, and machine-washability—so verify current absorbency specs directly on product pages before buying.

Some washable products already include a waterproof crotch and need no separate pad, while others hold a reusable liner. If you are not ready to sew your own, our tested roundup of the best women’s incontinence underwear options compares absorbency levels and fit notes to help you choose.

For any incontinence product, the NHS advises selecting based on the leak’s cause and amount rather than the product’s marketing. If DIY or store options are not controlling the problem, a clinician can help identify the underlying cause and suggest a pessary, a urethral insert, or a referral to a specialist.
