Sailor Lolita is a very well-known, standard sub-style of lolita, inspired by japanese school outfits combined with lolita fashion. Being such a standard style, every summer, almost every brand produces Sailor themed dresses and skirts and accessories - so they're easy t come by.
However, if you dont want to fork out for brand for a halloween co-ord, there are plenty options for cosplay accessories to adorn your existing pieces.
