Prom

I'm graduating this year, my prom will be 8th June. I have already an idea of what to wear. I want something cute, bold but still something that has to do with me. So that's why I'm a little stuck between a mint girly dress or a white boho one... Another issue are the shoes and bag, I don't want to buy new ones just for the prom and I don't know if I should go for the heels or flats. Either way, if the choice is any of these mint dresses I will be making a little bun with a pearl band, if I choose the boho ones maybe a laurel tiara or a flower crown. Either way I am really excited about this.
