My 16 y/o DD is in Y11 with prom coming up in June. Recently started looking at prom dresses online but as we are taking a trip into London this weekend told her not to order anything. Anyway she completely ignored me and ordered herself this www.coast-stores.com/lauder-jersey-maxi-dress//coast/fcp-product/2310005380 dress from coast in the sale. She absolutely loves it but I stupidly gave her an honest opinion and said I didn't like it as it was unflattering IMO (made her average sized boobs look huge). She has now been in a terrible mood since it arrived yesterday as she feels she has no choice but to send it back and so now need to get somewhere in London where I am guaranteed to find her a dress she will love! She is paying with savings and is willing to spend up to around £170-80 but wants it to be as cheap as possible as is also saving up for Leeds fest! Any recommendations of places to try? Was thinking kings road/oxford street, possibly brick lane for a 50's style vintage dress (or is there no point??) and someone also recommended Fonthill Road, is it worth a try? Thanks.
