I feel like my bottom cheeks are hanging out. How can this be fixed?

Thank you for your questions. It is hard to say without photos and not knowing what exactly is going on. You should follow up with your Plastic Surgeon to discuss your concerns. Good Luck. 

I generally prefer the Fajas which cover the buttocks completely to hold the shape without creating lines. Most of the times lines are not a big issue but if the lines are deep, pushing on the fat grafted areas, and consistently in the same spot, it can cause a contour deformity as the fat in that area may be resorbed. You can ask your surgeon if you need another faja or some extra padding to place under the creased areas. Hope this helps!
