As you all know Dasha Astafieva is January 2009 Playmate and also the 55th Anniversary Playmate. The Ukranian born brunette was in a pretty festive mood at the Playboy’s 55th birthday celebration the other day. Being a giving person that she is, she decided to treat her fans with a special gift: she hiked up her see-through dress and took off her thong! I guess Christmas came a little earlier this year! Enjoy the pics!
