My daughter (15) is going to be bridesmaid at a friend's wedding abroad this year. I've bought this dress for her, which is sage green, but I'm struggling to find sandals to go with it. Any ideas what colour would be best? We've tried nude and ivory, both look wrong. I'm thinking silver or white might work? What does everyone think? She's very slim, 5'7" and would like to wear a heel but not too high considering her age and height. Ideas welcome please.
