Black mens coat
I didn't expect such good quality from such an inexpensive black coat, stylish, neat, looks expensive, none of my friends believed that I bought it so cheaply! No pellets appeared after a year and a half of use

Has shoulder pads.
The jacket has shoulder pads that don't necessarily show on the image in the purchase area. Pretty pronounced so if that's not your thing definitely stay away. Got lucky and it doesn't look too bad on me but it took so long to receive the package I don't feel like going through the refund process so I'm dealing with it. Quality is great tho
