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.
