New without tags 96% wool, 4% elastane Clean single-button blazer, which we're calling our 'Perfect' blazer. It's neither too boxy nor too loose. It's tailored but not stiff and unlined for movement and lightness. We want you to wear this all the time: over your favorite t-shirt, silk cami, sweater, hoodie or dress and with jeans, a skirt or a more tailored pant.
