I have a student who makes a point of wearing her Kimono every weekend in the winter and Yukatta every weekend in the summer, since it's like 35c here O.o

she knows it's unusual but she loves wearing them

When she wears them it's not the way I'm used to seeing people wear them for special events, it's more comfortable and habitual for her, so she moves very gracefully and wears it more like skin than I'm used to seeing.
It's kind of like how an experienced businessman wears his suit compared to a university student going to his first few interviews haha.

Honestly the way the vast majority of Japanese people I meet wear their kimono and yukatta it seems awkward. Definitely compared to how people 100yrs ago might have.

Along the lines of what GoNative said though, if I go to a major train station I can probably spot one every hour or two.
