This woman's black textured stretch knit jersey jacket is by Misook from their Deluxe line for size XS. The jacket is new, the tag is still attached and it retailed for $458. It's a travel knit and is just gorgeous, there is bead work and silver threads on it. I took a close-up so you can see the material and the embellishments. 

25 inches long

17 1/2 inches wide from under ona arm to under the other across the back

23 inch sleeves
