I have two plus size bridesmaids in my wedding and need opinions on dresses...please help!?

I have been looking endlessly for a flattering dress for my girls. I found a dress from alfred angelo style 7016 that I think is really pretty but I'm not sure if this style would be appropriate for a plus sized figure or look like a maternity dress. Any opinions would be great...here is the link a href="http://www.alfredangelo.com/Collections/ProductDisplay.aspx?productID=08c98e2a-4340-45ad-a9f9-72589d86968e&categoryID=bfff30be-a493-4315-880c-45a86ae342b8&pg=0" rel="nofollow"http://www.alfredangelo.com/Collections/…/a
