They may dress loosely but do not act upon it.
Also they dress like that at weddings and baptisms etc. Day to do they wear clothes no different from any others. Jeans boots and a t shirt
The reason how I know your first statement is false, is because, I went to school with some gypsies in high school, they play that role...and they were screwing the gypsy dudes, they didn't eff with anybody else...as I said, All women have the potential to be whores, no woman has moral higher ups on any one. As a general rule of thumb, women dress like that for attention, they get attention, which is their goal. They may not be screwing around, but the implication is there.
Women and attention go together like fish and water....
Or another saying, women are always into something, or something is always in them...
