The gradual yet unstoppable process by which your wife or girlfriend
's clothes take over your wardrobe. It often begins by the male partner naiively agreeing that he will temporarily host a single garment because of a short term capacity issue in the female wardrobe. From this point on the male no longer has control of his wardrobe.
Becky: Darling, I'm just putting my long dress from Kirsty's wedding in your wardrobe - I've run out of hangers in mine. Is that ok?
Chris: Of course, go ahead
(Six months later, and the effects of wardrobe creep are clear)
Chris: Why is my wardrobe full yet I only own two items in it?
