It is very pretty, and I like it a lot. According to Sailor Civilian it's also Usagi's most commonly worn casual outfit. I also, like her purple skirt, pink blouse combo from Classic. If I had to pick, I generally like what Usagi wears the most out of the squad...though every character has a few great looks.
It is sad, Naoko was allowed to publish Sailor Moon with outfits without permission, but CLAMP got a strike when they initially tried to publish X as Hagun Seisenki due to issues in Intellectual Property.
