Not Always A Bridesmaid

I'm going to be a bridesmaid this coming summer and the bride is amazingly laid-back about the whole dress-thing, in fact, she sent me these suggestions, and made a special note that a lot of them are on sale. I do especially like the Lydia dress (yes, that would make sense), but I'm pretty sure my bust would not especially like it. I think I'll go for this one or this one... (in the pretty purple colour) Lovely!
