One of Ewa's recent promo emails said:
"WITNESS THE MOST SEXY AMATEUR GIRL EVER
UNHOOKING HER 75L CUP SIZE BRA"
Not sure what "75" refers to. There's no way Xenia is 75 inches across her breasts and it can't be centimeters, either, as that converts to a bit more than 29 inches, which is way to small to be her band size. But she looks like she could be an L cup.
