What about a little fake fur capelet with a pretty bow?

I agree with Khris; what you need is a cape, not a coat:) Whether you go for a capelet that just covers the shoulders, or a longer, waist-length number, capes will fit the formality of the gown and situation a bit more. Plus they feel so retro and fun to wear! :) I have a couple given to me by my Grandmother, but you can often find them in vintage and consignment stores these days.

Great idea! I'll have to check out ebay as well. All my ideas fell flat, she may actually like this one. Thank you, ladies!

A capelet is a good idea, but you might also consider a cute faux fur jacket since she'll be wearing a cocktail-length dress. Something 1960s-ish. She could wear the jacket with jeans after the event.

That's a good idea, too. I actually had my eye on one for myself a few weeks ago on ebay, and it relisted. My concern is she is soooo picky, though she is maturing (actually willing to wear heels/rhinestones AND have her hair done, unlike jr. high formals). I shouldn't complain, until 8th grade it wasn't cool to wear any coat no matter how cold it got, at least she's embracing warmth now.

She hadn't even planned on attending the dance til she was voted on the Court, so we're running around like fools to get this all done by next Friday.
