At a party celebrating Playboy’s 55th Birthday over the weekend, Hugh Hefner’s latest girlfriend, Dasha Astafieva, gave the world a taste of what her and Hef’s life must be like behind closed doors. The Ukrainian model showed up to the party wearing a very see-through, very tight black dress, with nothing under it except for one very lucky black thong. Everything except for her labia was on display.

But that wasn’t enough for Dasha. Once the bulbs started flashing, she decided the thong had to go. Her outfit simply wasn’t revealing enough! So she hiked up her skirt and, somewhat gracefully, made her underwear disappear. Magic.

Maybe it was making her a little too warm in the Vegas heat. Maybe she had one too many vodkas on the limo ride over. Maybe Ukrainian girls just love to show the world their vaginas. Really, we’ll never know. What we DO know is that this is one photo set you simply can’t miss, and that even at age 82, Hef still knows how to choose ‘em.
