I have a big France Luxe claw clip that will hold like a rock, so I'd probably just twist a pony and clip it up, but anything with your hair pulled back would work. I just got a silk snood from Etsy that covers your whole head--I got it so I could work in the yard if the wind is blowing hard--but I don't suppose you have time to order one, haha.

I hope you have/had fun! Your hair will be fine--sometimes fun is more important than hair (gasp! it's true!).
