Again, great sizing advice from Daisy, a size up from your normal one will give you room for another layer underneath. This is jacket is leather with stretchy panels on the arms and around the waist. It fits really well because of that and isn't stiff or heavy as a full-on leather jacket. They are two zips on the hips to flare out if you are wider on that part. Zips on the cuffs and Velcro to make good closure with your gloves. Two outside pockets with zip, plus back, shoulder, and elbow protectors. And a little flash of pink thrown in - which i love. Excellent jacket.
