Amazing quality!
Size: Medium, Color: Pinkish, Size: Medium, Color: Pinkish
Fabric super durable, genuine denim. Fit was a bit tight for the size but still looked perfect and easy to style/accessorize. Don't even like pink and it's a new favorite fit!

Order regular size. 6' tall, get a medium.
Size: Medium, Color: A3#white
It's a pretty good jean jacket. Sizing is the main issue, suggestions for what size to order very from ordering your normal size to order 2 sizes larger. I'm 6' tall and skinny, got a medium which is my regular size, this thing fits me just like the model, coming to my waistband with enough room to fit a hoodie underneath. Not sure why the seller is telling people to order 2 sizes up, since jean jackets are supposed to be a little bit short and thin compared to other jackets. One slight issue is the size of the button holes. 3 of mine were too small to fit the buttons through. Easy fix with a knife though. Material quality is good, it wasn't easy to cut. I dyed mine yellow and it took the dye quite well, if you're considering doing that with yours.

Too short
Size: XX-Large, Color: Black White
Well if your 6ft or taller it's very disappointing it's to short it doesn't fully let down to the waist it feels short your constantly asking yourself can you get away wearing it when you feel a little uncomfortabl. Return it maybe get a bigger size unfortunately for me there's nothing bigger than the 2xl bigger not longer
