This jacket looks really hot. The design is super classy but not overly dressy. It's cut like the jacket of a military dress uniform; it's fitted along the torso, upper chest and back. The sleeves are roomy. It gives a great silhouette. The only downside is that, just like a military uniform, you really can't abduct or extend your arms without almost ripping the shoulder seams.
I tried both the XS and the M, (both just don't let you do too much with your arms) and decided to keep both. One for formal evenings and one for casual evenings so I can layer up a bunch underneath.
I gave the coat 4 stars because the large buttons are barely sewn on securely. I would've liked a zipper underneath but oh well, definitely love it anyway.
