Checked one button blazer size 4 | H&M fitted blazer

Fully lined, tailored checked one button blazer. Cuffs have smaller matching buttons. Comes with an extra of each size of button. Very good condition. The only sign of wear is at the back vent, on the seam between the lining and outer fabric, there are a few strained threads. I have shown a close-up of this in the photos. Colour is a tight black and white weave with yellow windowpane check. H&M size 4. Smoke and pet free home.
