I ordered this on a whim and I’m so glad I did. Every piece actually fits and the quality is so much better than I expected. I’ve already worn three of the outfits to the gym this week.

Common Questions

Can I choose colors or styles?

No — each box is curated by size and current inventory. That’s the mystery (and honestly, part of the fun).

Is there a subscription?

No. One-time purchase, no recurring charges. Buy it when you want it.

Can I return it?

All sales are final due to the discounted pricing. If something arrives damaged or incorrect, reach out within 7 days and we’ll make it right.

How is this different from the 12-piece box?

The 12-piece box gives you more variety, a lower cost per item, and a matching set — but the 6-piece is the most popular starting point.

What size should I order?

S fits 0–4, M fits 6–8, L fits 10–12, XL fits 14–16. All styles run true to size. When in doubt, size up for the best fit through the hips.
