A quilted puffer coat in black or navy is the uniform of someone who has decided to look pulled together even when it is freezing. These are the versions that skip the oversized silhouette entirely and instead follow your shape closely without feeling restrictive. The quilting sits flush against the body rather than billowing outward which means you can actually move your arms without looking like you are wearing a sleeping bag. Synthetic fills provide genuine warmth without the weight that down adds. The result is a coat that works over dresses and tailored trousers with equal ease and actually fits properly under a blazer when you need it to.
