We spotted more than our fair share of athletic influences on Spring's runways — designers made sure to work mesh details, hoodies, anoraks, and neoprene surf pieces in with their separates — and with the Olympic Games well under way, it's even more tempting to get in on this year's ultrachic sportif trend. Sporty looks took on many different versions, from Isabel Marant's cool, colorful layers to Alexander Wang's perennial sporty-girl swagger. Narciso Rodriguez and Helmut Lang both incorporated sleek black and white color palettes into track pants and sports bras, while Phillip Lim's pretty pastel collection gave way to tailored pants, clean-cut tanks, and vinyl rain slickers. Even the normally coquettish designs of Victoria Beckham gave a nod to sophisticated activewear — her minimalist silhouettes, exposed zippers, and strong colorblocking really brought the trend home. In an effort to show off our sartorial prowess (as well as our Olympic pride), we've rounded up 21 of the chic sportif pieces that you need now — click through to shop them all.
