Care Guide: Seamless underwear uses ultra‑fine fibres and bonded construction for a smooth, second‑skin finish, so proper care is critical - especially for leakproof styles with bonded gussets. Wash cool (≤30°C) on delicate with gentle, pH‑neutral detergent, ideally in a mesh wash bag. Always air dry (tumble drying is an absolute no‑no) and keep away from direct heat/sunlight. Never use fabric softeners, bleach, or dryer sheets, and don’t iron or dry clean. Full care instructions can be found here.

FAQs
All FAQsAre they leakproof?
No. Seriously Seamless is all about comfort and zero lines. For light leak protection, shop Leakproof.
What are they made from? Are they cotton?
The main fabric is a soft, moisture-wicking nylon and elastane blend that stretches with you and dries faster than cotton. The lining is cotton, with an antimicrobial (silver ion treated) crotch that helps reduce odour-causing bacteria.
Will they ride up when I squat?
They're cut to stay put. The anti-wedgie shape and bonded edges reduce ride-up and wedgies compared with thongs and minimal cuts, and the right size helps the fabric lie flat. They're designed to be worn under leggings, not shorts: the fabric clings to your leggings to help them stay in place, which loose shorts can't do.
Will they show under my leggings?
Seamless construction is designed to minimise VPL and butt bulge. Very thin or sheer leggings may still show a little texture.
Will they help with chafing?
The seamless construction and moisture-wicking fabric are designed to reduce friction and keep you comfortable.
What size should I get?
Use our size guide and measure yourself, as "true to size" varies a lot between Australian brands. They're quite stretchy, so go with the size your measurements show for a sleek fit under leggings.
Are they camel-toe proof?
No, we didn't design them specifically for this, so if you're prone to it these may not be the right product.
Are they okay for sensitive skin?
Everyone's different, so we can't give specific advice. They're designed to reduce friction and manage moisture. If you have sensitivities, check the fabrics and care guide, ask your dermatologist if unsure, and stop wearing them if any irritation happens.
Can I tumble dry them?
Please don't! Cold wash at 30°C or below, delicate cycle, mild detergent, no softener, bleach or dryer sheets. Air dry only, away from heat and direct sun.
How long will they last?
It depends on how often you wear them and how you care for them. Following the care guide (no heat, no softener) keeps the bonding, stretch and performance going for longer.
Can I return or exchange them if I change my mind?
Yes, unopened pairs can be returned or exchanged within 14 days under our change of mind policy. You'll just need to cover the return postage, and for exchanges we'll send out your new pair at no extra cost.
