The Frankie Sweater Baby is a cosy, practical little jumper designed specifically for babies and toddlers. It’s worked from the top down, allowing you to adjust the length of the body and sleeves as you go — perfect for growing humans.
The construction is simple and clever, making this a really satisfying knit without being overwhelming. The fit is comfortable and roomy, ideal for layering over onesies and dresses, and it’s designed to be easy to get on and off wriggly babies.
This is a brilliant everyday sweater: warm, wearable, and endlessly gift-able.
