Zara lined snap front multi color blazer

This is a gorgeous blazer. I purchased for my mother however it was just a little bit too small. I purchased it gently used. It has not been worn since we purchased it. The buttons alternate designs. Has two pockets in the front. Is lined inside. The base color is navy blue however it has threads of multicolors. Pit to pit is 17 inches. Length from the shoulder is 20 inches.
