Size A cup

I used to be a size 32B a few years ago. I got pregnant and of coarse my breast got bigger.  After I stopped nursing my daughter I lost close to all of my boobs. I don't even fill an A cup now. I'm totally insecure when it comes to wearing certain clothing and I don't feel the least bit sexy in front of my husband. I'd like to get implants but want to be sure on done having kids first. I guess my question is-for those of you with smaller breasts-is there a certain bra you wear that makes your chest look larger so your not so uncomfortable with yourself? Really not looking forward to wearing tanks and loose clothing this summer. 😔
