About IRIS KIDS

IRIS KIDS began with a mother's love for her daughter.

We believe every child deserves the freedom to express their individuality while growing up surrounded by beauty, creativity, and comfort.

With a global perspective, we carefully curate thoughtfully designed childrenswear from talented designers around the world. Every piece is selected for its timeless style, premium quality, and everyday comfort.

More than beautiful clothing, we believe great design helps children grow with confidence, creativity, and the freedom to explore every adventure.

At IRIS KIDS, every collection is chosen with love—for families who value quality, originality, and meaningful design.

Product Story

There's a particular kind of thrill a child feels pulling on something bright for a birthday morning, and the Party Fun T-Shirt was made for exactly that feeling — a cheerful, colourful birthday-print tee that turns getting dressed into part of the celebration. Whether it's her own party or a friend's, this is the tee that gets picked first out of the drawer.

The relaxed, everyday fit and soft fabric mean it's just as at home the next morning as it was at the party — a shirt built for real movement, not just a photo. Verified across the size range, the bust sits between 34.5 and 44.5cm, sleeve between 10.5 and 14cm, and shoulder between 31 and 39cm, so the fit stays consistent from the smallest size up to XXXL.

Sized by height from 80cm to 140cm and cut true to size, the Party Fun T-Shirt earns its place well beyond a single celebration — a bright, easy layer for playground afternoons and quiet weekends alike.
