Breasts after weight loss

I’m currently 38dd, and I love my boobs. I’m trying to lose about 60 lbs though, and last time I was that small (about 2 years ago) I was only a C. I have a close friend who recently lost about the same amount of weight, and often complains how her boobs “deflated” and are just like flaps of fat, instead of round. She doesn’t really have lose skin anywhere else. I’m terrified mine will do the same, is there any way to avoid them becoming saggy and deflated??
