Lolita-ness to me seems to be looking like a young girl and perhaps being "sexually precocious" at the same time. This image of the japanese fashion called "Sweet Lolita," besides just the name, seems to fit the Lolita-ness because of the style. The soft pink and frills appear like what a children's doll used to look like or how little girls dressed a few years back. The childish clothes exude an attempt at looking like a sweet young girl. Which fits the first part and the placement of her hand and the half smile remind me of the character Lolita which by the author's definition means she is "sexually precocious."
