Rosie Roff has one of those bodies that doesn't seem physically possible. It's actually quite a bit unfair, like one person shouldn't be allowed to have so many absolutely perfect parts. The English/Irish/Czechoslovakian lingerie and bikini model seems to be well aware of this, since she's wearing next to nothing in most of her Instagram posts. Or even less -- seriously, the amount of totally nude shots is worth your time (uncensored versions of which just might be available on her Twitter, FYI).
