World Book Day is great. It’s also famous for turning up at the last minute, usually via a crumpled letter you’ve apparently “known about for weeks”.

Tu’s World Book Day shop is built for two kinds of parents: those who want a full costume in one go, and those who’d rather do a quick, comfy DIY look that still clearly says “character”.

If you want zero thinking, head straight for Costumes and pick something recognisable. If your child hates anything scratchy, or you’d rather buy items they’ll wear again, put together a DIY costume and clothing for easy building blocks like character T-shirts, sweats and dresses. Nightwear can also be a smart shortcut if school allows it.

For a quick formula, choose one “this is the character” item (costume, tee, dress or PJs), then add one extra detail from Tu’s accessories if needed (hat, cape, mask). Done.

The best part? You can now enjoy 20% off select World Book Day clothing at Tu until 1st March 2026.
