It’s working like a glove

This is a mix of the phrases “fits like a glove” (fits very well) and “works like a charm” (works just the way you intended).  Both phrases indicate things that are exactly right, so hence the confusion.  Also charm and glove are five letter words.   A big shout out to Tim Kunzler who uttered this beauty, and Marsha Roberts for ratting him out! 🙂
