Size: PM Buttons extend to below the chest, and are hidden for a clean look (only the top button is visible). Buttons on the cuffs. Lined skirt. I have a cat. I take great care to remove cat hair, but it's very good at sneaking in everywhere. Due to the nature of the product, it is impossible to completely remove all cat hair, and some will inevitably be present. Please refrain from purchasing if you have allergies. I would appreciate it if those who do not mind cat hair would consider purchasing. To reduce the risk of cat hair, I have not taken flat measurements.
