Yves Saint Laurent Rive Gauche from the 2000s. Not sure if Tom Ford or Stefano Pilati. Reminiscent of Fall 2004 Ready to Wear collection, with the ruched detail, military influence, covered buttons and epaulet cuffs. Sleeves are a bit long, as is intended to be worn. Pilati debuted with similar style shirts, so unclear whether this is Tom Ford era or Stefano Pilati era. (See runway.) Cotton/nylon/spandex Runs small. Fits like a US size 4 Bust: 34” Length: 24” Gently used. No flaws to note.
