Not just NY. I grew up in Minneapolis in the 1960s, and the same was true there. Might still be true there. When thong underwear arrived, it was called "thong underwear", "thong panties", or some such, to differentiate from thong footwear.People in the New York metropolitan region referred to flipflops as "thongs" in the 1960s and early 1970s.
