Spring Jacket, Toasted Coconut

Important sizing note first, because it really matters with this one: the Spring Jacket runs significantly oversized. You can afford to go at least two sizes down from your usual. Hil is normally a UK 10/12 and she's wearing the 34 (the smallest size). More on sizing below.

Now the jacket itself — and what a jacket. Y.A.S. is a Danish brand that has a knack for making one quietly extraordinary piece every season, and Spring is this season's. Cut from a substantial wool-blend twill in a soft, toasted-coconut beige, it has that architectural, almost sculptural cut you'd expect to see on a runway and then walk past in a shop window thinking I cannot possibly. You can. The asymmetric wrap front folds across the body like a piece of origami, the V-neck sits beautifully off the collarbone, and the dropped shoulder and slightly belled sleeve give the whole thing a quiet drama. Fully lined, cropped at the hip, finished to a standard that justifies the price.

This is a transitional piece in the truest sense — too warm to call a summer jacket, too elegant to call a winter coat. Throw it over a slip dress for a spring wedding, wear it with wide-leg trousers and trainers for lunch, layer it over jeans and a roll-neck come October. It is a wardrobe piece, not a passing fancy.
