Wedding guest

Hi! Super last minute post but would this be okay for a formal attire? I’m just a +1 for my bf’s bestfriend’s wedding today and was wondering if my outfit is ok! Would also ask if I should curl or straighten my hair? I’m a little chubby so I like my hair down… and also which bag to use? The brown one or silver. Thanks a lot!! Pls be nice to me 🥰
