Stradivarius teen sizing

[Dianmels]

Help please, I am about to order some trousers from Stradivarius for dd who's 12 and 5' 2" 158cm. I can't seem to decipher the teen size table. Should I go for XS?

Anyone?

I'm not 100% on teen sizing but I've always found Stradivarius to come up small. I always get the size above what I would get anywhere else.

I just looked at the website, I didn't realise they did teen sizes, on the website they have just number sizing from what I can see but if you click on the item it gives measurements. I would go by the measurements on some of the items it tells you the height of the model and what size they're wearing.
