Im a big chested guy somewhere around 42DDD or in to the Es(i haven't been measured in forever) ive tried the whole ace bandage thing... doesn't work so great. I have been looking into compression shirts but im not sure what would work best
any ideas?

Underworks lesloveboat and t-kingdom are some sites to check out for binders.

Personally I am a larger guy somewhere around a 38 D to a 38 DD sorry I don't measure them because I avoid paying attention to them but anyways I use Underworks The tri-top worked best for me but the double front works alright (they are just bouncier in the double front than the tri-top) but when I double up the double front (pull the bottom up over the top) it works really well.

Good luck on finding the right one for you!

I'm about a 44DD, so nearly the same size. I like the Underworks 997 (the double front), although I haven't tried anything else to compare it to (other than ace bandages which was a total failure). I do wear a sports bra underneath it to keep things from moving around, and it causes a bit of a uni-moob, but it makes me flatter. Since I'm a big guy (5'4", about 18 stone), I'm happy with making my chest flatter rather than flat, because without something there, it would look pretty odd for a man of my size.

I'm around a 36 F and I prefer the 997 from underworks. I have used a t-kingdom binder and they suck.
