A leather blazer should fit a woman perfectly, not too tight and too loose. It should comfortably hug your shoulders and fall smoothly down your back. The sleeves should end just past your wrist, and when buttoned, the blazer should close without pulling. Our classic Leather Blazer is designed for a relaxed and structured look, allowing you to wear it with just a t-shirt or layer with a sweater as you please. Please email us if you have specific sizing inquiries.
