A-line skirts and empire waists tend to look good on all body types. Except this choice, you could also consider choosing a color or a fabric and then letting each maid pick a plus size bridesmaid dress that will suit her. You wouldn't want to cram a tall, voluptuous bridesmaid into the exact same style as a petite, skinny girl (totally unfair to either). So that would be a better solution.

If you're considering strapless dresses or cheap bridesmaids’ dresses that don't accommodate bras, ask your bridal party if they would be comfortable in such a style before you decide. Don't be a control freak and try to do everything on your own. Appoint your maid of honor or a highly responsible bridesmaid to be in charge of organizing gown purchases. It is their bridesmaid dresses, which should absolutely care for their opinions.
