Hi hun, I had 375/400cc implants as i had a 1.8cm difference between my boobs. The difference in size has reduced drastically for me which is great. In terms of the dropping and fluffing, you are only 3 weeks post op you still have a long way to go. Your boobs will drop and fluff at different rates as technically you have had an operation on each boob. Just because they’re a pair doesn’t mean they do everything the same as we both know from having asymmetry. You will stress over this like a lot of other girls have but trust me it is perfectly natural. You will notice a lot of difference at six weeks plus 🙂 x
