Breast size - how to maintain? in a 15 lb weight loss

Hey

So I know that it is normal to lose breast size when losing weight

Is there a way to mitigate the cup size loss? I'm working on a 15-20 lb weight loss, not one of the 50+ lbs (which for sure you lose cup size in, its to be expected)

so given my smaller lb weight loss goal, is there hope? lol

hope some of u can share some personal experiences with me

thanks
