I am 5'10" and 210 lbs and got the XL. The fit is maybe a little bit small through the waist/chest, but overall it fits well.

This is a pretty decent $40 coat. It looks fashionable and is relatively slim-fitting, but you get what you pay for so don't expect the material and stitching to be comparable to a $100+ jacket. The material of the jacket itself is soft but pretty thin, so it might not keep you warm in extreme cold for extended periods of time. The buttons are sewn on pretty cheaply so if you can't re-sew them yourself or don't know somebody who can, I wouldn't recommend this jacket. The threads holding the shoulder straps down came undone almost immediately, and I expect that the front jacket buttons will come loose eventually too (though they haven't yet). Probably my only other complaint is that the sleeves are a little bit big and loose for a "slim fit" jacket, but I think that is my only complaint about the look of the jacket. The large lapels give it a pretty unique look, so be prepared to get some second glances and compliments on the look of the coat.

Overall- You get what you pay for. It's a nice looking coat, but don't expect it to hold up to extreme cold or heavy wear and tear.

The jacket fits perfect just slightly tight on I have all three buttons, so I only use two of the buttons and if I Get an XL. It will be too big.

It fits wonderfully and I will certainly be buying another color. I am 5'11", weigh ~180, and my chest size is ~42". I bought a large. Many reviewers said they can't lift their arms all the way up due to the tailoring; well it's a pea coat, not an athletic jacket that would provide more room for movement, so unless you plan on doing jumping jacks or rock climbing, then this coat is not for you. Other than that, if you want to stay somewhat warm and look good, get this!

I'm 5'3 and 106 pounds, I ordered a small. This jacket was pretty large on me but I know I won't find a smaller size in stores and definitely won't find one this cheap. It looks pretty nice, especially given the price point. Very comfortable. It's a great value and I will be keeping it, I'll need to make adjustments though.
Edit: I've decided to return it. I'm going to look for a children's coat instead. I feel like this coat is meant for people around 6 feet tall, 160+ lbs.

Buena calidad
