Help idk what to wear to my husbands work party

My husband has his company holiday party THIS SATURDAY and I don’t have a dress to wear yet. When we moved into our new house, our old one flooded and a lot of my dresses (amongst other things) were ruined in the flood. Nightmare. I have twins and they’re sick currently so I can’t go out to shop for one and need to do online. Don’t wanna spend a ton, I’m 5’2 and 105 pounds. Any ideas of places to shop? I’m looking on amazon prime haha 😆
