cousin getting married. was asked to be bridesmaid about a year and a half ago and i was chuffed (love a bit of wedding fever). at the time the bride said "don't worry, i won't make you wear bright orange or pink or anything like that". fast forward a year and a half later and the bride has chosen orange bridesmaid dresses. now the other bridesmaids are all darker and thinner and taller than me and the dresses look beautiful on them. tried mine on as well at the weekend and i look like a bloody carrot. i said at the time (without wanting to upset the bride) that it wasn't a colour i would normally wear and i was a bit worried that it didn't suit me. she and the other bridesmaids insisted i looked lovely and apparently it won't clash as much if i have my hair in a bun 
. took a few pictures to see if it looked any better on camera and it looked even worse. have shown other people the pictures and everyones reaction so far has been "oh bloody hell". i'm going to have to pay £130 for this dress that looks hideous. we haven't paid for the dresses yet, am i unreasonable to give her a call tonight and explain that i really don't like the dress even though i know she loves them?
if IABU, any advice on how i can get away with wearing this dress?
