What is Cosplaying? Here at Kawaii Stop, we wanted to share a little bit on just what is cosplaying and Cosplay. People who love a character will sometimes dress up as them on occasion. They will don the persona of the character and wear outfits that they have worn. Cosplaying has been extremely popular in recent years and has been making headlines all over the world. There are dedicated conventions for these fandoms where most people will wear multiple cosplays through a weekend. These events are extremely popular and are an absolute blast to go to! If you have not been to one then our team thinks you should go atleast once! Favorite sources include the following: anime, cartoons, comic books, manga, television series, and video games.
