Knickers for Teen Girls, Ages 8 to 15

Everyday knickers for teen girls aged 8 to 15 are the pairs that go under school uniform, PE kit and weekend clothes. They cover the years when she is growing quickly and needs underwear that keeps up. Sizes go by height rather than age, and an 8-year-old usually takes 134 cm. For socks and other basics, see the teen Underwear & Socks range.

If she is between two sizes, choose the larger one. Knickers that dig in at the waist or leg tend to get left in the drawer. Each size up is about 6 cm of height, so check her height every term during a growth spurt. The product page lists the fabric for each style, and the care label gives the washing instructions. Wash new pairs once before she wears them.

Your questions answered

The MINOTI teen knickers collection contains everyday knickers for girls aged 8 to 15, sold in centimetre sizes, with a 10-year-old girl usually taking 146 cm.

What size knickers should a 12-year-old wear?

A 12-year-old usually takes 158 cm. If she is tall for her age or between sizes, measure her height and pick the nearest size in centimetres. Go up a size rather than down.

How do I know when a teenage girl has outgrown her knickers?

Red marks at the waist or leg after a day's wear are the clearest sign. Each size is 6 cm taller than the last, so if she has grown that much since you last bought, move up; a 13-year-old usually takes 164 cm.
