I'll be honest, I couldn't really see the pic so I had to save it on my desktop and zoom in that way! Don't worry, I have deleted it now though, in case you think I'm a weird stalker woman.

They don't really suck it all in like support dresses and pants, they just give you a nicer clean line - I tend to buy them a size bigger so they reach up to my bra, then you don't get any tummy lines. Massively attractive as I'm sure you can imagine!
A bodyshaper dress would be super but I don't think they're cheap
