Prom!

I recently got a dress for my prom in a few days, but I have no idea which handbag to carry. I wish I didn't have to carry one, but I kind need to due to menstrual reasons lol. Anyways, I want to know you guys' opinion! I have silver shoes, bracelet and earrings to go with the dress (but I might change to black flats later, I'm not too good in heels 😅)

I'd also like to know you guys' opinions on the dress! Any hairstyle ideas? (I have quite thin hair, a little past shoulder length). I was thinking a mild curl with a low, loose-ish bun. Maybe with hair hanging in the fronts still?
