Do you leave the bottom button of a waistcoat unbuttoned?

A custom still sometimes practised is to leave the bottom button undone. Undoing the bottom button avoids stress to the bottom button when sitting down; when it is fastened, the bottom of the waistcoat pulls sideways causing wrinkling and bulging, since modern waistcoats are cut lower than old ones.
