The frilled apron is a type of cloak in NetHack brass. As it appears as an 'apron,' it can be an annoyance to players seeking an alchemy smock.

Though it provides no benefits of its own, the frilled apron, worn in conjunction with the maid dress by a female character, grants 4 bonus AC and magic resistance. This is a reference to the mythical status of French maids in anime. (Moe moe kyun.)

A male character who wears the frilled apron will only gain aggravate monster.
