TWEEN CLOTHING FAQ

What styles are available in size 11–12Y?

Our tween collection includes dresses, playsuits, shorts, pants, leggings, jackets, cardigans and selected swimwear. Styles and availability change, so check the size options shown on each product page.

Are Oobi’s tween clothes age-appropriate?

Yes. Oobi’s 11–12Y clothing is designed for girls who still want colour, comfort and fun without styles that feel too young or unnecessarily grown-up.

How do I choose the right size for an 11 or 12-year-old?

Check the garment size chart and fit notes on the individual product page, as measurements vary between dresses, jersey styles, outerwear and separates. If she is between sizes, use the garment measurements or ask us through chat for help.

Are Oobi’s 11–12Y clothes made from cotton?

Many Oobi tween styles are made from breathable cotton, including cotton jersey, poplin, corduroy and knitwear. Selected products such as swimwear use different fabrics for their specific purpose, so check each product page for the exact composition.

Colour, comfort and just the right amount of grown-up.

Tween Girls’ Clothes

Finding clothes for 11 and 12-year-old girls can feel oddly complicated. Too little-kid, too grown-up or mysteriously beige. Oobi sits happily in the colourful middle, with comfortable styles that feel fun, age-appropriate and easy to wear.

Explore colourful girls’ dresses, cartwheel-ready shorts and playsuits, comfy pants, leggings and skirts, plus soft cotton jersey clothing for everyday adventures.

Our 11–12Y collection includes party dresses, relaxed separates, jackets, cardigans and selected swimwear. Each garment has its own measurements and fit notes, because tweens grow according to their own mysterious schedule.

Oobi is an independent Australian children’s label and has been voted Australia’s Favourite Children’s Fashion Brand seven times by Kids Style File. Colourful clothes, comfortable fits and childhood firmly left in charge.
