Good quality
Size: Medium, Color: Navy
I gave this as a Christmas present and he loved it. I was worried when I ordered it that the quality might not be that good, but I worried for nothing.

This is more like a long cardigan sweater, than a coat.
Size: Small, Color: #2 Blackandwhite
This is more like a long cardigan sweater, than a coat. It doesn't have much structure & the pocket placement is too high for a coat. That being said, it's very soft & comfortable. As far as sizing goes, the sleeves run a bit long, but the coat, itself, runs a bit tight. I'm 5'10'' and a small fit me, but I wouldn't be able wear anything very thick under it & I'm thin. It's light & machine washable. I almost kept it to wear as a long sweater, but it looks like a coat ,so I sent it back. If you're very thin with long arms and don't mind the pockets being a bit high, then this could be a very stylish piece for you. Otherwise, I would pass.

i would definitely recommend. stick with your regular size or size up for a less slim fit
Size: Small, Color: Black
I usually wear a medium, I ordered a small based on reading the reviews. I am 150lbs 5’4”. this coat fits great for me personally. it’s not bulky, it’s not baggy. it is a slim fit jacket, definitely more on the slender side. when i raise my arms above my head , the sleeves do come up a bit. I would suggest sticking to your normal size or if you want a less slim fit with a tiny bit more room, sizing up wouldn’t be an issue. the coat is super soft and has some weight to it. i would recommend this jacket, it is warm and a nice piece for formal attire.
