#oshima tsumugi

Super chic kimono outfit, with a soft pink tsukesage (houmongi?) with lovely black patterns with just the right hints of colors, paired with that AMAZING obi.

I didn’t know about that technique, but those are called mugetsu obi (lit. “moonless sky” obi), and this style was first used to decorate shawls. The patterns are made by sewing on cord-like trim in appliqué:
