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.

Great coat
Size: Large, Color: Black
Sizing runs true, the quality appears to be good. I ordered the black and the color is what I expected, it’s the perfect length. The weight and thickness is perfect for temperatures in the low 30’s and up. The coat is perfect for Business wear and casual wear

Warm and Stylish
Size: X-Large, Color: Khaki
Perfect for dressing up ay outfit. Comes folded in a bag with tons of wrinkles, so leave time for dry cleaning if purchasing for an occasion.
