If there’s one gift fashion shows afford the average viewer, it’s the innovative styling ideas they often yield. And one particular technique that’s been pervading the runways is styling an outfit over a long-underwear-type, heat-tech-like, very tight, long-sleeve shirt (often with a turtleneck addition). For pre-fall 2015, they came in bright colors beneath Miu Miu’s collection, all sequined and shiny under Dior’s, and in a stark black underneath J.W. Anderson’s. Yet it’s still the latex that peeped out from Marc by Marc Jacobs’ spring 2015 collection that has left the strongest impression. This latex, long-sleeve mock turtleneck is the closest you’ll come to those eye-catching, spanking garments, and the most affordable option out there too.
