Common questions

When will my order arrive?

Each tee is made to order, then shipped, and usually arrives within 3-5 working days (further-away countries can take a little longer). You'll get a tracking link by email as soon as it's on its way.

How much is delivery?

Delivery is free worldwide, with tracking included, no matter where you are or how much you order.

How do I choose the right size?

Every product page has a size guide in centimetres. Our tees are unisex and true to size - if you like a relaxed fit, simply size up. Still unsure? Message us and we'll help you pick.

How do I care for my tee?

Wash inside out at 30°C with similar colours, and avoid ironing directly over the print. Hang to dry where you can. Treated well, the print stays bright and crack-free for years.

What's your returns policy?

Because each tee is printed just for you, we can't accept returns for a change of mind - but if there's ever a print fault or your order arrives damaged, visit our contact page with a photo and we'll reprint or refund it, no fuss.

Can I talk to a real human?

Always. Our UK support team replies to most emails within a few hours, Monday to Saturday - reach us via our contact page.
