Let's talk about structure: until I found this bra, I was convinced that any bra without underwire would make my breasts look and feel saggy. When I finally tried the Bravado! Designs Women's Bliss Nursing Bra ($35), I was proven wrong; instead of underwire, Bravado uses Flexi-Fit™, which are "under-breast support channels." But it's the cups that are molded with foam that give the shape; it's not so thick that they add bulk to your silhouette, and the fabric is perfectly smooth under tees and thin tops.
