Generally speaking from my experience, the Dominican women wear more "form fitting" clothes, as well as the whole hair thing... And what I mean by that is, the amount of time they will spend worried about their hair, is nowhere near what a gringa will spend, time or money wise working on/playing with/colouring/ or putting extensions into their hair, including the frequency with which all the "tune ups" are required for the lid! The Dominicana's live for the friggin salon, to an extent unparalleled, I dare say, by any other cultural women.
On a side note, should a Dominicana see another woman hitting on her man, I've seen more than one go from 0-100 in lightspeed.
