Is it ok to wear a ... to ... ?
X means no.  O means yes.  A ^Triangle^ means maybe.

Translated from Utsukushiikimono.
This list is by no means encompassing, but it should answer a lot of questions on kimono-wearing in Japan.  It's up to you to decide if pertinent. I'd like to point out that an iromuji or nice komon is probably the most versatile piece for this list of events. The least versatile? Kurotomesode.
Notes:
Tsumugi (pongee) is a serious category. Could be a recent trend 'cuz I don't remember it being as emphasized five-ten years ago (during the meisen craze).  Shima is 'stripes', muji is 'plain' or monochrome.  Tea party is 'o-cha-kai', Practice means kitsuke practice probably.  Graduation ceremony also includes school entrance ceremonies & escorting/chaperon(e) - I don't think it's for graduates, but rather relatives, teachers, well-wishers...
