Ladies aaaand gentlemen, welcome to spring’s first smack down — a no-holds-barred, all-out tug-of-war. In one corner, we have lightweight tanks and jersey dresses dying to show their stuff. In the other, heavy sweaters and cable-knit tights (still the season’s reigning champs). Tired of refereeing your closet’s battle? Call a truce with Soïa & Kyo’s new collection of trenches, jackets, and blazers. The little sister line of Montreal-based Mackage keeps it in the family with A-line shapes, oversize buttons, and waist-cinching belts. Top a filmy blouse with a fitted blazer or lighten knits with a cream cotton trench. Just-right weights and water-resistant finishes are as practical as they are polished. So even when March winds whip your hair into a rat’s nest, you won’t skip a beat. Because from the neck down at least, you’ll still be a total knockout.
