I Am Looking For A Dress To Wear To My Boyfriends Brothers Wedding.i Live In Glasgow And Need Help!?

i am a size 10-12 but have quite big boobs so strapless isnt an option.i am only 5 foot so prefer knee length because anything longer drowns me. all the dresses i have seen are black but i want something summery because the weddings in august.i know i wont have money then so want to buy now.i am trying to keep to a budget of £100 but will go higher if i fall in love with it! to give you an idea i loved this dress http://www.cruiseclothing.co.uk/erol.htm… (D&G silk dress £360)except i dont want black and its too expensive! thanks in advance
