NWT Quadrille couture denim linen blazer

NWT Quadrille denim (blue) linen blazer. This blazer is simply gorgeous! It is beautifully made. The material is linen (denim is the color not the fabric). I believe it to be lined with silk, but there is no fabric tag because it is couture, so it’s just a guess. It is definitely a designer size 10 - so truly a 6 or maybe a small 8. I was unable to button across my chest and I’m a 12 🤦🏻‍♀️
