At a plastic surgery clinic in Upper Manhattan that caters to Dominicans, one of the most popular procedures is an operation to lift women’s buttocks, because — as the doctor explains — “they all like the curve.”

In Flushing, Queens, surgeons have their attention trained a few feet higher, on upturned noses that their Chinese patients want flipped down. Russian women in Bay Ridge, Brooklyn, are having their breasts enlarged, while Koreans in Chinatown are having jaw lines slimmed.

As the demand for surgical enhancement explodes around the world, New York has developed a host of niche markets that allow the city’s many immigrants to get tucks and tweaks that are carefully tailored to their cultural preferences and ideals of beauty. Just as they can find Lebanese grape leaves or bowls of Vietnamese pho that taste of home, immigrants can locate surgeons able to recreate the cleavage of Thalía, the Mexican singer, or the bright eyes of Lee Hyori, the Korean pop star.
