How old is "Anastasia"?

I met Anastasia at Zeds bar over the weekend. She is one smokin chick, were goin out again on Friday. I invited Zed over to HOAI and asked him to post photos of his girls, he knows tons of em! Anyway, Anastasias in her 20s let see if you can guess her age

Anastasia is a pretty girl, with blonde locks and white complexion. She's a medium lady with a fit body, pert bootie and a nice bust.
