Questions, answered.

What is Toffee?

A limited-edition rich, dark brown in our SmoothFit range, in five styles: Bikini Brief, Full Brief, Thong, Boyleg and Padded Bra.

What is SmoothFit made of?

Organically grown bamboo viscose: incredibly soft, breathable and moisture-wicking, so you stay cool and dry all day. The seamfree finish won’t dig in or leave lines under clothes.

Is Toffee limited edition?

Yes. Toffee is a limited run. Once a size sells out it may not come back, so if you have a favourite style, grab it.

Can I mix styles in one pack?

Yes. Pick 4 or 7 pairs, tap Build your own pack, then choose a size and tap a style to fill each spot. Every piece keeps the size you picked for it, so your bra and briefs can be different sizes.

How do I pick my size?

Tap Size guide beside the sizes. The briefs, thong and boyleg share one chart and the Padded Bra has its own. The bra is a fitted cut, so if you’re between sizes, size up.

How does the First Pair Guarantee work?

We are so confident you'll love your first pair of Step One underwear that if you don't, you can keep them and we'll give you a full refund. No questions asked. This applies to your first single pair purchase.

How should I wash them?

Machine wash cold with like colours. Tumble dry low or line dry in the shade. Do not bleach, iron or dry clean.
