Another Muromachi kosode. In all the first three pictures, note the different length of the kosode worn under the outer layer and how much it varies. Can you see how the left okumi and end of the collar is folded back to show the lining?
Mo, without karaginu(??!?) Looks like a ceremony- maybe at a shrine like Ise??? It's like, uwagi and mo, but no karaginu jacket... ??? Info, anyone? They appear to be priestesses (ceremonial objects in hand), so this may be a priestess-only thing?
