Looks like normal exposure to me, normal sex appeal. Thailand, and other Asian countries, can't and won't always stay traditionally "cooped-up" in what is considered taboo to them, or immoral...orrrr whatever they want to call it. It's called the entertainment business, modeling hits high top in one of it. And sex appeal means money.
So, HELL, if they wanna look like lesbos, let them be free! Lol, cuz they're lookin hawt!
