How long will my T-shirt take to arrive?
Each T-shirt is made to order, just for you. Production takes care and time and so your item will be mostly dispatched within 4 weeks but please allow up to 10 weeks. As soon as it’s on its way, we’ll send you tracking info so you can follow every step of its journey.
How will my T-shirt be packaged?
Your T-shirt will arrive neatly folded in a secure envelope, carefully packaged to protect it in transit. We’ve tested multiple packaging methods - this one keeps your T-shirt safe, flat, and looking its best.
How should I care for my T-shirt?
Gentle care preserves the quality, colour, and shape of your garment and helps it last far beyond fast fashion.
- Wash inside out on a cold or 40° cycle with similar colours.
- Use non-chlorine bleach only if needed.
- Hang dry, avoid the tumble dryer; it’s the worst.
- Iron inside out on medium heat and never directly on the print.
- Do not dry clean.
Are these T-shirts sustainable?
Yes, and proudly so. Each T-shirt is crafted with 100% organic cotton, meeting globally recognised sustainability standards (OCS & RCS). They're soft, durable, and made to last, just like the art they feature. Better for the planet, better for your wardrobe.
What is the policy on returns?
Each T-shirt is made to order especially for you, so we can’t accept returns for a change of mind. However, if your T-shirt arrives damaged or with a rare defect, we’ll replace it straight away. Your satisfaction is guaranteed.
What if my T-shirt gets damaged in transit?
If your T-shirt is damaged in transit, we’ll send a replacement free of charge. We’ll just ask for a quick photo or video so we can claim the insurance from the shipping provider.
How long will this T-shirt be available for?
Until midnight on 17th December 2025 or until the entire edition sells out - whichever comes first. Once it’s gone, it’s gone. There are no plans to restock.
Will my order arrive before Christmas?
Your order should arrive ahead of Christmas. While we can't offer an absolute guarantee, we operate on a best endeavours basis and we cannot refund orders that do not. Our delivery partners are reliable and fast and deliver within a week to most countries. Orders placed up until 12th December should arrive pre-Christmas.
