Do you have any beloved wardrobe items that you feel are especially glamorous, stunning or stylish, and that always make you feel super fab?

I live an extremely casual life but I have a couple items that make me swoon: a deep plum-colored velvet overcoat, and a wide-leg, long sleeve jumpsuit with impeccable drape. The coat I wear often in the winter; the jumpsuit, not as much as it's pretty dressy.

What are your showstopper items? How often do you wear them, and where? How do you feel when you wear them?
