How tight to I have to wear my compression garments after a BBL? Will it affect the way I walk?

Hello dear!!
Thanks for the question and provided information as well.
Every doctor has their preferences in regards to compression garments. I suggest my patients use a full body compression garment (that closes with clips), 24/7 for the first 3 months, and after that, for 12 hours a day for 3 more months, to get the best results. It wont affect your walking.
It is important for the compression garment to be very tight, for it to help with the swelling, after surgery, and to use it with a cotton t-shirt underneath to avoid garment burns.
Please, follow up close with your plastic surgeon.
Good luck :)
