Dropping means when your implants start to relax and settle in you boobies; initially a lot of ladies say they feel like two big hard rocks sitting under their chin, dropping is when they start to soften and sit In a more natural position!
Fluffing is when either your breast tissue or muscle adapt to the implant and it starts to appear larger! You got more fluffing with unders as once your muscle starts to relax the implants appear! Lots of ladies with unders find their pbies are t their true size until they hit around 8 weeks! Ladies with overs fluff too!:D
Hope this helps!:D xxx
