Definitely NOT the COLOR that’s advertised but not bad
I got this for my son for him to have his 1st official “dressy” coat for certain occasions. It will do for the price, but as I said in the description, it’s definitely not the color that’s shown in the advertisement. Its also not taken in like the picture. But not bad. It’s more of a camel color than a khaki like the advertisement. My son is 5’9 and has a slim build, I bought a L because he’s tall and this fits fine to be honest. I want him to be able to grow into it next year as well. If you have long arms you may wanna size up.

Nothing i wrote my comments above a statement above
Size: XX-Large, Color: Navy Blue
This item was not good quality, so I decided to not not use. It came pretty much wrinkled and folded in some package. And once again, it was not good quality was all wrinkled up you had to Send it to the cleaners to straighten it out and it didn't fit very well. It just wasn't there very good quality, kind of heavy, so so\n I'm not sure if I'll return it or just donate it to the local church. Thank you art cruz

Fantastic product... fantastic fit !
Size: X-Large, Color: Black
First off, China got this product from their country to ours, then to my hometown.... faster than my own post office could get it across town after much bickering. So... thank you to the Chinese. Complaints about America being better... then start doing better. Secondly the coat was far superior than I even suspected. It fit well and I cannot wait until cooler weather to break it out ! Again... thank you China ! Highly recommend this product.
