Wedding is not for ages yet, but don't have a clue where to start looking. Dd will be 13, slim but with 30e boobs. She doesn't want little girl dresses, but too young for topshop ish stuff. Any suggestions?
I would try asos. You can narrow it down by sleeve length, skirt type etc and see what sort of shape you're looking for e.g. skater dress with elbow length sleeves, t shirt length sleeves and so on. They've got everything on there including places like New Look and Hollister which sell clothing teenagers can wear.
I also like apricotonline.co.uk - they've got plenty of printed dresses which are quite ageless (maybe not right now as it's all quite wintery but in summer they do!)
