I didn't manage to sort this all out in time for Ayacon so I'm not sure when I'll wear it now, probably Fushicon if I don't have anything else planned. My main worry was getting the mandarin collar right. I think what I'll do now is buy a mandarin collar shirt and mod the top with it that way. I haven't succeeded very well at making the puffs in the sleeves so far but the top need to be fitted to me more so I can tweak them then.
There isn't too much left to do on it now, just need that shirt, make the cuffs (get some more ribbon for them too) and add the white edging around the bottom of the top.
