FAQ
When will my order ship?
Most orders ship within 1–2 business days. You’ll get a tracking email as soon as your label is created.
What is your return policy?
Return unworn, unwashed items with our tag intact within 14 days of delivery for review. Once confirmed, we process a refund to the original payment method.
How do you authenticate Supreme?
We verify tags, season codes, print technique, fabric, stitching, hardware, and perform a UV scan. Each item is dual-auth signed off.
How do I choose the right size?
Use the measurements on each product page. Fit notes (TTS, boxy, slim) come from wear tests and returns data.
