Controlled compression after liposuction is important for predictable long term results. Having said that, there are a plethora of garments available for purchase on the Internet and/or your physicians office. They range from simple elastic binders to elaborate zip up garments. Providing even, wrinkle free compression is most important. In patients who have had liposuction of their flanks (love handles) I typically recommend an elastic binder which provide a little more compression than biking shorts.
After 2-3 weeks of compression, patients will then transition into biking shorts or spanks. The flank area tends to retain edema (swelling) for a prolonged period of time, so persisted compression facilitates your recovery. Every surgeon has a different protocol for post op recovery, I highly recommend you call your surgeon and ask for his/her advice on compression. I'm sure he/she will be pleased to assist you during your recovery.
Best of luck!
