Like Mary Blair, Frida Kahlo's influence reaches far and wide. I don't know for certain but she may have pioneered the idea of flowers in hair.
There's various tutorials online making a flower headband like the flowers she used in her hair like this one by My Poppet
Reem Acra did advertisements inspired by her.
College Fashion did an in depth post on her.
Dolce &Gabanna created this awesome dress for summer 2014.
And wedding photographers around how Frida- weddings on their site like this one from 100 layer cake. (photo by Beth Olson Creative)
