The bottom button should remain undone. The vest should just cover the waistband so that no shirt shows between the vest and trousers. It works just as well as part of a three-piece suit under a jacket as it does on its own over a shirt.

Vests are not washable and should be dry cleaned. Iron at low temperature only. Detailed care instructions are available on each product page.
