Sorry if this has been done before but I've got a 10 year old DD and she is desperate for some Hollister stuff for her birthday. She is v tall but a little on the chunky size (i'm hoping its a growing phase....). She fits 11-12 at Mini Boden so would she be a small or a medium?? I'm thinking of hoodie/polo shirts but I'm running out of time! Any suggestions v v welcome!!! Thanks v much!
