Zara TRE Pearl Snap short sleeve blouse approximate size S burgundy, gray, blue

Zara TRE pearl snap blouse, short cap sleeves, pockets on chest, string tie on the sleeves. Cowgirl Up! Perfect with denim shorts, jeans and boots! The tags have been cut off, so I’m estimating the size at small. Please use measurements as a guide for your decision-making. This plaid shirt has burgundy, burnt, orange, gray, and brown with a line of light blue plaid. Also estimating the fabric as cotton, there is no stretch to it and is very light in weight.
