Clothing to wear after abdominal liposuction?

Evening. I'm getting abdominal liposuction in a week and I was wondering what kind of clothes I should wear. I figured that leggings would be okay, and dresses? One week after the operation I'm going to my graduation party, and thought that a shift dress would work well in order to hide the compression garment. Any other tips in regards to clothing and how I can hide the garment ? Im keeping this operation entirely secret. Thank you for your help.
