Been having something like this set on my mind for awhile. I wouldn't want the items ready until sometime in March, which should allow for some time to get the items finished. I'd want at least one recolor of all four items. Possibly interested in commissioning different artists for each item, but really hoping to find someone for all of it.
I am also interested in possibly co-releasing with the artist if they're inclined, to lessen the cost upfront by sharing profits.
Spring & Summer Yukata Set
Wig:

Hairpiece: No good way to put it in here, so LINK/
Yukata:
Spring:
but in pink
Summer:
just the pattern, in red or navy
Handheld Fan: More plain? We can discuss. 
I'd be willing to work with you on the set! I've been wanting to try my hand at a yukata or kimono cw for quite a while, and these are cute! I'm comfortable with working on everything except for the hairpiece - I'd rather leave that to someone better skilled at working on small, detailed items. I could do the CI for it, though, so all the CIs will be a matching set if that's something the other artist (and you) would be interested in.
Here's a link to my shop for some examples of my prior work and an idea of my pricing/policies. Thank you for considering!
