Tyler Silk Blouse

I am new to L'Agence brand and will not repurchase. I bought a 100% silk blouse with 3/4 sleeves and I sized up to XL for layering. I received a size medium with the inside tag at the waist cut so the true size of the blouse was not visible. So I purchased what I was led to believe was an XL, removed from the box, held it up and said aloud NO WAY this is XL. Mis-labeled without even removing from hanger. That is why it is deeply discounted. The material, while silk, is thin and the disappointment made worse because the blouse is so small it cannot even be buttoned closed. L'Agence size guide says XL is 12-14......Yeah right....discount passed off for the return pile. Buyer beware
