It's a COS for Celebration for U.S. Style Lovers!

COS stores have become one of the fashion flock's must-visit overseas shopping drop-ins, thanks to the label's effortless, pared-down basics. Now you don't have to hop on a flight to snap up the coveted pieces: This month the H&M-owned brand, which stands for Collection of Style, is debuting stateside with Cosstores.com (and its lower prices are coming too). "Minimalism is a timeless trend," says head womenswear designer Karin Gustafsson. "That's why each piece lasts season after season." The way to make it fresh, she says, is how you wear it.

To shop COS goodies, like our favorites shown here (above and below), head over to cosstores.com.
