St. John satin black pocket tee Designer

Classic style by St John from Nordstrom. This is from the collection bot sport line. It's in like new condition and I paid $300. Black shiny satin made of 78% triacetate/22%polyester. It's a heavier weight great worn alone or layered. Approximate measures 18.5" across chest and 22.5" length, the sleeve is slightly longer. I've kept hoping to wear again but too small for me, my loss.
