Dress with a 20's style but not fancy dress. Help!

[Pinkkahori]

Hi, I am going to a 30th birthday soon. The theme is 20's style but not full-on fancy dress.
Has anyone any suggestions? I am mid-40s and size 18.
Budget around £50. I like black, would prefer sleeves but not a deal breaker without.
Thanks

would something like this work?

Thanks. I love that but it's out of stock in my size.

i think that may have been a knock off of this dress here. it has more sizes avaliable x

As it’s not full fancy dress I would probably wear a dress that I already have or will wear again with a feather in my hair and some pearls. Maybe gloves if you want to go that far.
Do you have anything that could be jazzed up?
