Okay can I talk about my binder for a sec?
I’m a 34D, so all binders are awkward for me. Small band, large cup. So I never get quite flat, but some lumpy monstrosity with underboob poking out. But this one gets me the closest to flat while being the most comfortable binder I own.
And it looks like a tanktop!! And it was $10!!
It’s got stretchy bits on one side, and a line of bra-like clasps on the other that you can adjust to three different sizes, again like a bra. I didn’t overheat or even really sweat even when wearing it under a shirt in early summer pre-storm humidity. And once you get yourself situated just right, you can’t tell the tank is actually a binder.
EDIT: Here’s the link!
I have this version (an almost the same cup size as OP) an I can say that it is my favorite binder, as far as flatness goes. The clasps under the right arm chaff oddly for me, so I had to add a strip of padding (pretty invisible, if you need to know how I can show you)
