A few days ago I also went to an event with my tea ceremony group. It was their tenth anniversary and a Sensei was sent from Kyoto to teach us. It was great. There was a celebratory banquet held in his honor and I was able to wear kimono to that, though the pictures didn't come out very well.
I wish I could wear kimono for my actual tea ceremony events and lessons but unfortunately I'm too thick and therefore my kimono don't fit me in the way that my teacher wants me to wear them. maybe in 40 or 50 lbs!
