Every surgeon has his or her preference of how to manage garments. I typically requested patient keep on the garment up until 72 hours after the surgery. Then the garment is worn about 23 hours a day for the next six weeks. It should be okay for you to take off your garment periodically doing today.
Compression garments should be worm a minimum of 3-4 weeks following a liposuction procedure. However, every surgeon has his or her individual protocol for after surgery instructions. Be sure to follow your surgeon's instructions.
