You have 30 days from delivery to return any unworn, unwashed item with tags attached. Return postage is paid by the buyer, unless your item arrived damaged, wrong, or never arrived — in those cases we replace it or refund you in full and cover the postage. No restocking fees.
Approved refunds go back to your original payment method within 5–10 business days. See the full Refund Policy.
Unisex relaxed fit, sizes S to 3XL. True to size for a relaxed look; go one size up for the oversized, boxy 90s look.
Heavyweight 100% cotton, garment dyed and preshrunk. Wash cold inside out, tumble dry low. Every blank is dyed in batches, so the exact shade of wash varies slightly piece to piece — that is the vintage look, not a defect.
