I just ordered my wedding dress (Alfed Angelo style 2083). It's a fit-and-flair dress and I want a slip under it to make the skirt look more full. I tried it on in the store with one of their slips but I hated the slip (it was a drawstring "one size fits all" and wasn't comfortable). The slip made the dress look really nice though; it was a not-very-full A-line slip and because the dress is fit-and-flair it squished the slip at the top and made it stick out more at the bottom.
I've read reviews that David's Bridal slips tend to fit well but I don't know how I should go about buying them. They sell two slips that could possibly work, a "medium fullness" A-line slip (which looks a lot more full than the one I tried on) and a mermaid slip (which is tight to the knees; my dress is only tight through the hips). Should I bring my AA gown into the David's store to try on slips, or should I just buy both slips and try them under the gown at home? I'm worried because David's does not have the best return policy and I don't want to wind up with two $100 slips that don't work.
