Quick answer
The fastest way to ruin a bra or brief is heat and harsh chemistry: hot water, dryer heat and chlorine bleach all attack the elastane that gives shape and stretch. Wash in cool water with a gentle detergent, skip the dryer, and air-dry flat or line-dry. That one change does more for keeping bra elastic and brief elastic care than any specialty product.
Why elastic fails before the fabric does
Elastane is what lets a bra band and brief waistband stretch and return. It is also the first component to go. Heat, harsh detergent and mechanical friction all break it down, which is why an otherwise good bra can lose its shape while the fabric still looks fine. Once the band relaxes, the bra no longer supports properly and the brief starts to slide. That is the real cost of underwear care mistakes: you replace items that still look wearable.
The dryer is the biggest single mistake
Tumble drying is the most common cause of stretched-out bands and waistbands. The heat and tumbling combine to relax elastane and distort the shape of cups and seams. If you take one action from this article, make it this: stop putting bras and briefs in the dryer. Air-drying flat or on a line preserves the fit you paid for. It also prevents the pilling and friction damage that makes cotton briefs like the Body Cotton Bikini feel rough long before the fabric is worn out.

Detergent and bleach choices matter more than you think
Chlorine bleach is not a stain remover you should use on lingerie. It attacks elastane and can yellow white fabrics, which is the opposite of what most people want from a white brief. Use a gentle, bleach-free detergent and skip fabric softener, which leaves a coating that reduces stretch and breathability. For everyday cotton styles, a small amount of mild detergent in cool water is enough. If you are washing a structured bra, keep the hooks fastened and use a mesh bag to stop the band catching on other items.
How to wash and dry without wrecking shape
Wash bras and briefs in cool water, either by hand or on a delicate cycle. Hot water is the enemy of elastic, so there is no benefit to washing lingerie hot. After washing, press water out gently instead of wringing. Reshape cups by hand and dry flat or hang so the weight of the wet fabric does not pull the band out of shape. Rotate between at least three or four bras so each one gets a rest day; elastic recovers better when it is not stretched continuously. This is also the simplest way to extend underwear life across your whole drawer.
Myths vs. verdicts
- Hot water sanitises lingerie: Hot water does not make lingerie cleaner in any way that matters, and it is one of the fastest ways to break down elastane in a bra band or brief waistband. Verdict: myth. Use cool water.
- The dryer is fine on low: Even low heat plus tumbling relaxes elastic and distorts cup and seam shape over time. Air-drying flat or on a line avoids both heat and friction. Verdict: myth. Skip the dryer entirely for bras and briefs.
- Bleach is the only way to keep whites white: Chlorine bleach attacks elastane and can yellow white fabrics. A gentle, bleach-free detergent in cool water is the safer routine for white cotton briefs. Verdict: myth. Choose bleach-free care instead.
Products that reward careful washing
- Body Cotton Bikini - White: Body Cotton Bikini - White is made from lightweight cotton (90% cotton, 10% elastane) and is designed to reduce lines under clothing. The 10% elastane is what gives the brief its stretch and recovery, so cool washing and air-drying directly protect the fit and the line-free look.
- Push Up Pads Enhancement Products: Push Up Pads Enhancement Products are curved to hug the breasts securely and add up to one full cup size, with no slipping or shifting when used as directed. These pads are accessories, not garments, so they do not go through the wash cycle. Wipe them clean and store them flat to keep the curve intact, and check the enclosed instructions before use.
