Sweet Lolita or "Amaloli" ( アマーロリ ) is heavily influenced by Rococo styles as well as Victorian and Edwardian children's clothing. Focusing on the child and fantasy aspects of Lolita, the Sweet Lolita style adopts the basic Lolita format and uses lighter colors.
It has all the traditional lolita elements but with a more wider choice of colors, like light pinks, baby blues, whites, and even sometimes colors like lavender, canary yellow and mint green. This is also where you'll find the most fluff and frill.
