Stella McCartney for H&M tailored women’s blazer

This is a rarity and a very special piece from my dress up dress down collection! Stella McCartney for H&M black one button tailored laser in like new condition. The only thing is the size tag is missing. My estimate is that it is between a size 4 to 6 US . I am 5’9” tall and approximately 134 pounds and it fits me perfectly buttoned or unbuttoned. From Pitt to cuff is 17 inches shoulder to shoulder 17 inches as well . Top to bottom 28 inches. Please feel free to message me with any questions! This is truly a treasure for whomever buys it!!!
