I only have three bridesmaids, but with VERY different body types... one is 6'2" and very thin, another's 5'8" and a bit on the heavy side, and the other one's 5'2" and wears about a size six. (I feel like I'm dressing the three bears or something, lol) I have no idea what will look good on all of them! I like the idea of just telling the girls to just choose their own dress, as long as it's purple and appropriate for a wedding, but my mom insists this is horribly tacky. To further complicate things, one of the girls is a full time college student and another works at a very low paying job, so I feel bad asking them to shell out a sizeable amount of cash for something they'll only wear once... which again, is one reason I like the choose-your-own-dress idea. They've all got good taste, I'm sure nobody is going to choose something horrendous.
So, to sum things up... any ideas for three differently shaped bridesmaids on a tight budget for a mostly-purple-themed laid back (but still pretty traditional) outdoor summer wedding?
