Sizes, shipping and returns, the short version.
How do Mumzers sizes run?
Setzers, Teezers, Trouzers and Breezers come in 1-2Y to 7-8Y. Swimzers go from 1-2Y to 13-14Y, and some prints up to 15-16Y. Baby Onezers come in months: 0-3, 3-6, 6-9 and 9-12 months. Our kids’ pieces are cut slightly oversized, so they grow with your child. Between sizes? Size up. Each product page shows the sizes for that piece.
What are Mumzers made of?
Setzers and Trouzers are made from comfy, durable fabrics built for play. Breezers are lightweight and ultra-soft. Swimzers use durable, quick-dry fabrics with super-soft linings. Baby Onezers are 100% cotton. The exact fabric and care instructions are on each product page.
How does mix and match work?
Every Mumzers piece is made to mix. Swap the tops between two Setzers and you’ve got four outfits.
