Peony Tsumugi
Purple, pink and blue peonies woven on a yellow and white ground. This kimono has slightly longer sleeves than usual.

Closer view of the weave, with more detail visible. Peonies are the emblem of high spring and also symbolize femininity.
Closeups of the weave: the photo was taken on the side, so the weft threads (white) are vertical and the warp threads (dyed before weaving) horizontal. I don't know what type of tsumugi this is - it's difficult to tell from available resources. Although these photos don't show any nubs typical of tsumugi, there are some visible elsewhere on the kimono.
