Compression garments and BBL
At just a few days post Brazilian butt lift, it is not unusual for the injection sites to look somewhat weird or uneven. However, if you feel your garment is displacing the fat or causing a crease to form, be sure to check back with your surgeon for their advice. Best wishes.
Garment after BBL
I think that you need to ask your surgeon about the garment. I know that some have used cut outs, but many garments are now made specifically for BBL.
