What makes this crop of Spring tees cooler than the rest? They're just built better — literally. The Spring '13 runways, from Tibi to Alexander Wang, crafted their tees with structure — boxy, sculpted shoulders and neoprene fabrics made these more substantial than any cotton variety. The, shall we say, elevated construction also means they're well suited to a variety of occasions, aka not just reserved for your weekend denim routine. In fact, in floral prints, bright hues, and even with laser-cut detailing, these t-shirts are begging to be dressed up with your cropped trousers and pencil skirts and taken to the office, date night, and beyond.
