OmooneWomen's Oversized Mid Long Denim Jacket Jean Biker Coat

I’m 5”2 128-132 pounds I want the oversized look should I get a medium or large?

The comments on the smell of it makes me hesitant because I'm very sensitive to odors and that's a deal breaker. Has anyone else experienced that?

I love this jacket. Can l get it in 3x?

Hello! Is the material 100% cotton? Does it stretches?
