Questions, answered.

What is Trick Treaters?

Our limited-edition kids Halloween print: a patch of grinning pumpkins in purple, green, pink and orange. It comes in the boys’ Junior Trunk (ages 4 to 14) and the Girls Shortie (ages 6 to 14).

Can the grown-ups match?

Almost. Creole Conjurings is our adult Halloween print, in the men’s Boxer Brief and the women’s Bikini Brief. Both are on this page, so you can sort the whole house in one order.

Is it limited edition?

Yes. Trick Treaters and Creole Conjurings are limited Halloween runs. Once a size sells out it may not come back, so if you have your eye on it, grab it.

How do kids sizes work?

Kids sizes run by age: 4-5, 6-7, 8-10, 10-12 and 12-14 for the Junior Trunk, and 6-7 to 12-14 for the Girls Shortie. They are a fitted cut, so if your kid is between sizes, size up.

What are they made of?

95% bamboo viscose and 5% spandex: soft, breathable and moisture-wicking, and gentle on sensitive skin. Anti-chafe panels and a super-soft waistband mean no complaining.

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.
