Quick answer
Wash knickers in cold water on a delicate cycle or by hand, use a mesh bag, and skip the dryer. Turn them inside out before washing to protect lace and colour. Heat and harsh detergent are the main causes of fading and stretched elastic, so cold water and air drying are your best habits.
Knickers take more abuse than almost anything else in your drawer: repeated washing, tight waistbands, and friction against jeans. That's why colour fading and stretched elastic show up fast. The good news is that how you wash and dry them matters more than how much you spend.
This guide walks through a simple care routine that works for everyday cotton, silky scuba, power mesh, and lace-trimmed styles. You'll also see how specific fabrics in our range respond to washing, so you can adjust the routine without overthinking it.
Why elastic and colour fail first
Elastic is made of rubber or elastane strands wrapped in fabric. Heat, chlorine, and detergent residue break those strands down, which is why waistbands go slack long before the fabric wears out. Colour fades for a similar reason: dye molecules are washed away by hot water and agitated against other clothes.
The fix isn't complicated. Cold water slows dye release, a mesh bag reduces friction, and air drying removes the heat that kills stretch. If you only change one thing, stop putting knickers in the dryer.
- Check the care label first; if it says hand wash, believe it.
- New dark or bright knickers may release a little dye in the first few washes, so wash them separately.
Sort by fabric, not just colour
Most knickers can be washed together, but lace, power mesh, and silky scuba fabrics snag easily on zips and hooks. Keep those pieces in a mesh bag or wash them in a separate small load. Heavy items like jeans and towels should never share a load with delicate knickers.
If you're washing a set like the Holly Set - Sangria, check whether the bralette and knicker have different fabric content. The bralette uses soft lace lined with power mesh, while the knicker style may vary. When in doubt, wash the whole set on the gentlest cycle so colours stay matched.
Holly Set - Sangria
- Turn knickers inside out to protect the outside surface and lace trim.
- Fasten hooks and close zips on other garments before adding them to the load.
Choose the right detergent and temperature
Use a gentle, bleach-free detergent. Enzyme-heavy or chlorine-based products can degrade elastic over time. For hand washing, a small amount of mild soap is enough; you don't need suds to get knickers clean.
Cold water is the default for every fabric in our range, including the silky scuba used in the Amy Tanga Knicker - White and the four-way power mesh in the Emily Cheeky Knicker - Black. If a label allows warm, keep it below 30°C and never use hot water on lace or mesh.
- Skip fabric softener; it coats elastic and reduces stretch over time.
- Measure detergent rather than pouring freely, especially for small loads.
Hand wash vs machine wash
Hand washing is safest for lace, mesh, and anything with delicate straps. Fill a basin with cold water, add a drop of gentle detergent, and gently squeeze the water through the fabric for about a minute. Rinse until the water runs clear, then press out excess water with a towel. Never wring or twist.
If you machine wash, use a mesh bag and a delicate cycle with a low spin speed. A 15-minute cycle is plenty. The Sophie G-String is fully adjustable, so check that the hardware isn't catching on other items before it goes in the bag.
- Never leave knickers soaking for hours; dye can bleed and elastic can weaken.
- Wash light and dark items separately for the first few washes.
Drying without damage
Air drying is the single best way to preserve underwear elastic. Lay knickers flat on a towel or hang them by the waistband in a shaded spot. Direct sunlight can fade bright colours, so keep them out of strong sun.
If you must use a dryer, choose the lowest heat setting and remove items while slightly damp. But for anything with lace, mesh, or a delicate waistband, skip the dryer entirely. The small time saving isn't worth replacing stretched-out favourites.
- Reshape lace edges while damp so they dry flat.
- Hang by the waistband rather than the leg openings to avoid stretching.
Storing knickers to protect shape
Once dry, fold knickers and store them flat in a drawer. Hanging them by the waistband for long periods can stretch elastic, and cramming them into a tight space causes lace to snag. If you stack them, put delicate pieces on top.
For sets, keep the bralette and knicker together so you can grab a matching pair without digging. A divider or small drawer organizer helps, but even a simple folded stack works if you rotate what you wear.
- Avoid storing damp knickers; make sure they are completely dry first.
- Rotate your everyday pairs so no single pair wears out first.
Your 6-step knicker care routine
- 1. Check the label and sort: Read the care label and separate darks, lights, and delicates. Put lace, mesh, and silky fabrics into a mesh bag before they go near the machine. Common mistake: tossing everything in one load and hoping for the best.
- 2. Turn inside out and fasten: Turn each pair inside out and fasten any hooks or adjustable straps. This protects the outer surface and stops hardware from snagging other items. Checkpoint: no loose straps or exposed hooks before washing.
- 3. Wash cold and gentle: Use cold water, a mild bleach-free detergent, and a delicate cycle or hand wash. Skip fabric softener, which coats elastic and reduces stretch over time. Common mistake: using hot water or too much detergent, which speeds up fading.
- 4. Rinse and remove promptly: If hand washing, rinse until the water runs clear. If machine washing, take knickers out as soon as the cycle ends. Don't leave them sitting wet in the drum. Checkpoint: no detergent residue left in the fabric.
- 5. Press, don't wring: Gently press water out with a clean towel. Never twist or wring, which distorts lace and stretches elastic. Common mistake: wringing hard to speed up drying.
- 6. Air dry flat or hang by the waistband: Lay flat on a towel or hang by the waistband in the shade. Avoid direct sun and the dryer, especially for lace and mesh styles. Checkpoint: completely dry before folding and storing.
Fabric notes from our range
- Emily Cheeky Knicker - Black: Made from luxurious four-way power mesh, which is extremely soft to the touch, with a lace front statement. We recommend sizing up in this knicker. Power mesh is durable but can snag, so wash it in a mesh bag and air dry to keep the lace front looking crisp. Sizing up also reduces strain on the elastic.
- Amy Tanga Knicker - White: Crafted with silky soft scuba fabric and adorned with a delicate lace band. White scuba shows dye transfer easily, so wash it separately from dark colours and treat stains promptly to avoid fading or greying.
- Sophie G-String: Fully adjustable for the perfect fit; made from a soft, stretchy fabric that provides comfort and support. Adjustable hardware can catch on lace in the wash, so fasten it or use a mesh bag to prevent snags and keep the stretch intact.
A consistent cold-water, air-dry routine keeps colours richer and elastic springier for far longer. Start with one mesh bag and one drying rack, and you'll notice the difference within a few washes.
