This season, knits in the form of corsets, with hourglass fits and underwires galore, and cropped half-sweaters are reigning supreme on Instagram. Whereas choosing between turtlenecks, cardigans, and V-neck pullovers used to make up the choices involved in building a sweater wardrobe, options now extend even to the lingerie drawer, with knit bras and full knit garter sets currently available. Prairie collar sweaters are replacing your standard crewnecks, and scarves come attached to sweaters, rather than in addition to them.
