Here is a gorgeous short sleeve blouse by Papell Boutique Evening. The shell is silk, the lining is polyester. Wonderful bead work on a thin, sheer layer (silk) over a cream colored under layer (poly). A zipper in the back goes almost the length of the shirt from the top. It's medium weight and in great shape with tons of life left! The tag says Small, but here are the measurements when laying flat (please see the last picture for how we measure shirts)

Chest 18"
Sleeve Length 9"
Length 24"
