    Great!
    Color: Black, Size: Large
    I needed a blazer for a last second professional presentation and it looked great! my peers thought I rented this since the quality looked very good. I love the inner pocket and it fits pretty good! the color also goes very well with the rest of my clothes, it’s not shiny at all!

    Runs small good quality
    Bought for my husband to wear to an event however was to tight in the arms. He has bigger biceps so this is not for someone who works out. It does seem to be a nicely made jacket for the price though. The material was soft, not many wrinkles. A quick light steam would take them out. The color was spot on from what the photos showed and looked great with the vest we purchased from the company. Layering was no issue with its weight. As always, returns were easy. Thanks Amazon
