An Alexander McQueen blazer, especially in timeless Prince of Wales check, is indispensable to the busy woman's wardrobe. An object lesson in the label's exceptional tailoring, this one is made from wool and cashmere, and fully lined in satin for the perfect fit. The low button stance serves to elongate the frame; meanwhile, narrow peak lapels, a nipped-in-waist, and angled side pockets create a slimming effect. You won't think twice before putting this on when your day is full of appointments.
