frequently asked questions

The Everyday Brief offers full coverage on the back and a wider side panel, making it the best choice for all-day comfort under any outfit. The Everyday Cheeky has a narrower back panel that sits higher on the cheek, giving a slightly more revealing look while still being comfortable for daily wear. If you want maximum coverage, go Brief. If you want a balance of coverage and shape,go Cheeky.

The Everyday Brief is not a seamless/no-show style, but it uses flat-bonded seams that significantly reduce visible panty lines compared to traditional underwear. Under most fabrics(denim, thicker knits, darker colours) lines will not show. Under very thin, light-coloured, or body-hugging fabrics, a thong may be a better choice for a completely invisible look.

If you prefer a snugger, more secure fit, go for the smaller size. If you prefer a more relaxed,easy fit, choose the larger size. If you’re not sure, we offer free exchanges so you can try both.

Our gusset is approximately 2cm wider than the industry standard, meaning more coverage for comfort and hygiene. It does not mean the underwear is longer — just that the gusset panel itself provides more surface area.
