No.....not necessarily. In fact Russian gals are not all that.....buxom. Ukrainians, on the other hand, are. As the expression about them goes "pol-nah pah-zoo-khah tsitsok" (полна пазуха цицок) which means "lots of bosom behind the blouse".
Ukrainian girls.....they are something.

This is why The Beatles sang "The Ukraine girls really knocked me out" . They sure can.
