A normal back brace doesn't seem like a good solution, or at least, not the ones I've seen in stores. I have terrible scoliosis, and now that I've decided to transition, I thought a back brace would be a better solution to my problem than my regular corset. Unfortunately, the only ones they had were of pretty universal sizes, and so it was a bit big on my waist, and had a lot of extra wrap-around velcro. It would have been tighter on my chest, but I still don't think it would have been tight enough to work well. Plus is was pretty bulky and awkward.
I use my neoprene waist belt when I'm working. I usually wear cocoa butter under it, which helps me to burn off breast fat while I'm moving.
I think I've lost almost a cup size so far. But the cocoa butter also makes it slide around more (as does the sweat it causes), so I need to wear a sports bra overtop of it (which sucks, but I find it better overall for appearance, as it keeps the velcro part from popping up and looking tumorous). I wore it on my bike ride yesterday and literally dripped sweat all down my body when I took it off (it didn't hinder my workout, either, so I like it). Of course, the neoprene even by itself will make you sweat in the right conditions (as mentioned above me), so this is something to consider if you're trying to stay clean. That's why I want to make my own, just without the neoprene. Also, that way I can make it to better fit me. Of course, I'm putting it off because I just hate having to sew things.
