Abstract
Abstract This invention relates to a fly structure for trousers or the like, and more particularly to a fly structure formed from flaps which are integral with the front panels of the trousers or the like. The flap forming the outer or exposed flap portion of the fly is folded in a manner to provide reinforcement along the free edge and to simulate the construction obtained using fly flap pieces independent of the front panels of the trousers or the like.
