Help me find a bridesmaid dress!

[GetTheeToANunnery]

My sister is getting married in September and has asked me to be bridesmaid! I can pretty much choose what I want as long as its not a dull colour and nothing to over the top.
I'm 23,size 12 (but will hopefully be a 10 by then), small boobs, pale skin tone although she wants me to get a spray tan :(

Everything I've seen is a bit naff or to fancy. They're getting married in a registry office btw.

Please help!

My wedding dress was a bridesmaids dress....was fitted at top n could either wear it with or without straps, was a kinda a line shape n came with a matching shawl...was lilac in colour and I got it from debenhams bridal wear for less than £100 :-)). Not sure if that helps!!

lots of choice at coast

budget? colours that suit you? any bits of your body you want to show/hide...

Budget is about £70 but I wouldn't mind adding another £70 ourselves. Not really sure of my colours, anything but red, bright pink or yellow really.
I'm happy with most bits of my body apart from my boobs!

I saw an advert on fb the other day from damsel in a dress . A bride had four girls in a silver dress from there . They looked amazing .. I'll see if I can find it .
