Is this a fashion or something? Because the word lolita has nothing to do with this?
Lolita is a Japanese fashion styled after Victorian and Rococo dress styles. It’s incredibly popular amongst certain types of people the world over.
There’s a numerous styles of it; gothic, country, pirate, sweet, sailor, classic, punk, guro and so on.
Have a look at the Derpibooru “lolita fashion” tag (that I spent this morning cleaning out).
