Dress look, without paying, big dollars!
Size: XX-Large, Color: Khaki
Well worth the $. With a sweater, perfectly fine for winter wear. Without a sweater? Perfect for fall Nice look You’ll need to have it ironed, in that it comes in a very small plastic. Minor ironing! A good buy!!

Very nice jacket/coat for the price
Size: X-Large, Color: Black
This was purchased to wear with a tuxedo for northern winter wear. The size XL is what he normally wears. It fit well over a tux shirt, vest and jacket. The length is perfect for a man; it covers the tux but does not get tangled in knees. It is lined in a satiny fabric. The wool type material is a bit rough, not soft, but it does the job. The black is rich looking and provides warmth for really cold weather. This jacket can easily be worn for casual wear. Should only be dry cleaned, but doubt it will ever really need to be cleaned.

Actually violet color and looks nothing like picture
Size: Large, Color: Red
Bait-n-switch. What arrives looks nothing like the photo. Its purple/pink and a misshapen ladies coat. Really low quality. And why they make them 90% polyester is crazy - just waiting to explode in flames!

Better than expected
Size: Large, Color: Black
Nice weight and kept me warm in 20 degree weather. I recommend adding a scarf for your neck line but this coat gives a nice clean but dramatic look.
