Sixteen pairs of overalls, jumpsuits and other one-piece wonders

This spring, tops and trousers are being replaced with a simpler uniform. Practical one-pieces (not to be confused with onesies) are suddenly appropriate for every occasion, whether it’s a day at the office or a night on the town. And for busy Torontonians, the one-piece outfits make for effortless style—they’re insanely easy to throw on over basic turtlenecks, plain white tees or nothing at all. Here, the season’s best fitted flared overalls, work-appropriate jumpsuits and utilitarian prison-style suits.
