Hey Mo
You sound like you are very close to my size so I will let you know how a couple different binders worked for me.
http://www.underworks.com/ultimate-chest-binder-tankI had this one in black, size Large. It worked really well for going out - it really got me flat and also provided the mid-section compression too. Definitely only a short term thing though, would never want to wear it to sleep or for a really long day. It did restrict somewhat. But it was easily tucked in to my pants and rarely rolled up - only if I was really moving around.

It only has the compression in the chest, your midsection is simply in the cotton tank. More comfortable, didn't restrict me really at all. But like I said, at times the full compression of the other binder made me feel a bit more secure in terms of holding everything in.
These are the only two I ever used since they did the job and the price was right. And they should last you your year until surgery. I'm actually sending mine in to this program - maybe you can look into it if you're in need.
