There should be plenty of threads on it already if you look around, but if you google "lolita fashion" you'll see tons of articles. Google image search is typically crappy for visual examples but I find searching "lolita" on tumblr is full of more current ones.
Lolita fashion (ロリータ・ファッション Rorīta fasshon?) is a fashion subculture originating in Japan that is based on Victorian-era clothing as well as costumes from the Rococo period, but the style has expanded greatly beyond Japan. Companies such as Milk and Pretty (currently known as Angelic Pretty) sell various Lolita fashions.  The Lolita look began primarily as one of modesty with a focus on quality in both material and manufacture of garments.
Lolita fashion has evolved into several different sub styles and has a subculture that is present in many parts of the world. Although many people point to Japan for the Lolita trend especially with the influence of Anime media, which made it more popular, as the creator of the “Lolita Fashion,” the origin of its meaning is complex, and remains unclear.
The fashion is thought to have been partly created to react against the growing exposure of the body and skin in modern society. Adherents fight this with modesty, presenting themselves as "cute" or "elegant" rather than "sexy"
