Perfect buy!
Fit Type: Regular, Size: Large, Color: White
This white denim jacket came today, and finally I bought the perfect jacket! It's actual denim, heavy but not too bulky. It fits perfectly, I bought a large, it's white not off white, and it is EXACTLY what I was looking for! I had to wait a week or two but it is definitely worth the wait! Beautiful jacket, well made and at a decent price! Thanks Amazon Essentials!

Love denim and tired of cropped jackets?
Fit Type: Oversized, Size: Large, Color: Medium Blue Vintage
I like this a lot, it was what I was looking for as far as I'm so over everything you buy these days is cropped. Cropped styles are great, but are kind of getting old for some things in my opinion. The jacket is big as far as how it fits. I am 5'8" about 180 and I wish I would have got a medium, I got a large. The large is big and roomy enough that I could even wear ear a thick hoodie under it if I wanted to. However, the length is good as what I was looking for. The upper arms are large. However, this is a great quality denim jacket. Nice and thick, sturdy material (which I wanted). It's also at a great, competitive low price even if it's not on sale. Don't believe me, go ahead and search jean jackets. You'll see a ton, but I looked too and the quality did not look as good as this and plus the other jackets were a lot more for a lot less. If you're looking for a longer jean jacket, I highly recommend this. I'd say just think seriously about sizing down 1... even maybe 2 sizes. I would have gotten an XL before I read the other reviews. They recommended to size down, and after getting my jacket I could have sized down to a medium. I'm still happy with it and this is a jacket that is stitched well and will last a very long time. As always though, that's just my 2 cents. :)

Nice quality, shape not for me
Fit Type: Oversized, Size: Medium, Color: Medium Blue Vintage
This was just too boxy for my body. Material was nice, quality jean material. Color was true to image. It was a little stiff but as you would expect with nice, new and unwashed denim.

Solid basic good denim jacket
Fit Type: Regular, Size: X-Large, Color: Authentic Medium Wash
In direct comparison to Levi’s women’s trucker denim jacket, this one is: slightly heavier denim, less stretchy, less fitted. I kept this one and returned the Levi’s because I wanted the roomier fit. I wish it was a little longer in the body: I’m tall, and it isn’t too short but I’d like a little more length. It feels slightly longer than the Levi’s. I wish the sleeves were longer too. They are probably just right for an average height or shorter person. The armholes could be smaller. The medium wash is a nice medium blue, fairly even in tone. It doesn’t have a lot of stretch but it’s comfortable. The denim is substantial but not too stiff. Overall, it’s a standard good quality denim jacket without any peculiar style elements or weird cut. It’s good!

Fabric way to heavy.
Fit Type: Regular, Size: Medium, Color: White
Cute, but material is WAY to heavy, like the heaviest duty denim I've ever seen. Wanted this to be a cute coverup. If you're needing something while breaking broncos or riding your motorcycle would probably be great. I kept it for a while because it was good quality and well made, but it ended up in the donation pile as I'd never wear this.
