Age 11 jeans, adults in primark?

[Mummysharkdoodoodoo]

Dd has outgrown her jeans. She’s tall and slim. She’s nearly 11 and just going into age 11. Im thinking of looking in primark as they do lengths in the adult range. Do you think a size 4 would fit?

I take a 4 and I'm 5ft, 92 lbs and 24 inch waist if that helps!!

My DD4 is 11 and very tall for age (around 5'5") and slim (but not skinny) and Primark size 4 jeans and trousers fit her perfectly.

My dd found the shorts were perfect this summer in a size 4. She is 10 and very slim but has hips and thighs which aren't accommodated in most children's clothes. She's too short unfortunately for the jeans but someone taller would probably fit into them very well.

My 11 year old fits size 4 Primark. Where did my baby go?
