I have two tri tops from Underworks. The extra small cuts into my shoulders and sides, rubbing sores and leaving scars. Its worth it for me though, to have a flat chest. I don't condone it however.
I've used duct tape, control top pantyhose, compression shorts, ace bandages...each have their benefits and turnoffs. Tape crackles when you move, control top pantyhose cut off circulation...compression shorts, well, I don't know but they don't work, and ace bandages don't stay in one place. Most of those are damaging, especially tape. DO NOT use tape...I'm a self destructive ->-bleeped-<- on a rampage to attain my dream...if it means killing myself in the process.
Overall the tritop is your best bet in terms of binding. I don't know how big I am, but the extra small works best for me in terms of binding, but not comfort. Oh well.
