I have a long tank style one, link
I absolutely love mine, it works amazingly. I'm an A cup (if even that) and it binds me perfectly flat without much pressure at all, it's evenly distributed and comfortable. The length is nice because it helps push my hip fat upwards, giving me a more masculine shape. However I usually pull up the bottom part and pull it over the chest area, because the compression on my stomach gives me a sour stomach after a few hours. I'd HIGHLY recommend their stuff if you're smaller chested though, I really can't say how well they'd work for larger bodied folk.
