I ordered this bra, as well as the Anita microfiber nursing bra. Both bras are unlined, which I knew ahead of time, but we're literally talking one layer of sheer fabric. Most of my "unlined" bras are either double-layered, or just made of a thicker fabric. Surprisingly, this one holds up my 36DD's quite comfortably. The sling that holds you up while the cups are down is more supportive than in any other nursing bra I own, some of which look a lot more structured than this bra. It's easy to unhook, comfortable, and attractive as long as you're not wearing a t-shirt, cause it shows everything. So, if you're looking for a comfortable, supportive, unlined bra, the Anita 5035 is great.
(The microfiber one is useless-it's going back. It feels like its made out of pantyhose.)
