Hair corsages are the go-to look for a classic lolita. To me they posses a fairy tale charm and elegance. It's as if, at any moment, the girl is going to burst out into song and have a little blue jay land on their finger, singing along with her. The brand, Victorian Maiden, almost exclusively sells different arrangements of flowers as their hair accessories. Flowers can be worn by anyone with any hairstyle. Plus, there's the added bonus of being inexpensive and easy to make. Here are some lolita tutorials on how to add some flora to your look.
The Victorian Era even utilized a language with flowers! Check out this website to put a little meaning in your hair accessories.
Here are some lovely lolita models using hair corsages. All are from Victorian Maiden except the top two which are Mary Magdalene.
