Kassl's modern take on the blazer as outerwear, here made in their soft poly taffeta that gives this lightly padded coat a hint of sheen.  It has slant welt pockets and a peak lapel, with a shoulder construction that is accommodating to layers.  100% poly.  Dry cleaning recommended.  34=XS 36=small 38=medium.  Generously sized by design.  Margot is 5'4" and wearing the 36.
