After losing weight, can I make my breasts less saggy?

Hello all!
I'm in the process of losing weight, and I've noticed an unfortunate side effect...my ladyparts are saggy. Like...nipples almost pointed to the floor saggy, and I'm only 29 :( Several years ago, I had gotten up to 230, and managed to get down to 171. I let myself get back to 211, and am now back down to 178. (It was 175 a week ago, grr!!) Anyway, while I keep diligently working towards my goal of 130, is there any help for the twins? Any specific exercises that will make them perkier and fuller? Any tips or techniques would be highly appreciated! Thank you! Tweet
