Traditional kimono? I like the colors and the collar is on the right way, so that makes me very happy ^^ The pattern on the kimono sleeves is also on good areas. One major feature of kimono that I don't see here is the obi bow at the back. You can search "obi musubi" for that, there are many different ones. The most common ones are possibly chou musubi and taiko musubi. "Musubanai" (https://www.instagram.com/p/Bwb6N-JACRT/) is an exception to having a bow but it is such a new thing that I don't know much about it at all.

Traditional kimono are also obviously full length ^^; but I get that having long socks here is a feature you wanted to have.
