You are swelling from liposuction and may not see any changes yet. You will actually be your most swollen by the end of the first week. I am sure your surgeon discussed this with you. Be patient.
Don't let your skin wrinkle under your compression garment, but try to stretch it out. Use foam padding if needed. You are swollen now, but you don't want the wrinkles to stay unless you have too much loose skin.
