Where can i get lovely bridesmaids dresses?
I like therosedress.com, they have measurement charts to match to your bridesmaids measurements, that way you get the right size. Most formal dresses run small, I am surprised that yours are too big. Try to get them altered though, it can be done. My FSIL had me in her wedding and ordered me a size 12 dress, although I had worn a 6 to prom just a few months before. I told her it was too big, and when it came in it fell straight off, frictionless. It was enormous. It cost $80 to alter, but it fit after that. So, they can take dresses down many sizes. If the bridesmaids are similar sizes, maybe you can try to swap some around so that you have to alter the fewest number of dresses.
