MEXX Metropolitan Floral Watercolour Blazer

This is a pretty white shorter peplum classic blazer by MEXX with pretty watercolour floral print, 2 buttons.. It's lined inside and in mint condition and high quality. It says the size is CA 34. Not sure what that means but It fits like a size small. For reference I am 5"2, 115 lbs and 36C and it fits me perfectly. Not too snug, not too loose. Perfect for summer and the office.
