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.

Old school denim — not stretchy
Fit Type: Regular, Size: X-Small, Color: Authentic Medium Wash
Fabric used is old school denim — not the thin, stretchy stuff that pretty much everything called “denim” is today. It is 99% cotton (20% of which is recycled cotton) and 1% elastane, but I can’t feel any stretch in the fabric. It is a substantial, non-stretchy denim that gives the jacket really good structure. It has a higher end fit and look than the price would suggest. I wanted a more fitted denim jacket so ordered an XS even though according to the size chart I need a small. (I have a 34.5” bust, 28” waist at 118 pounds 5’4”.) It still buttons over a t shirt or lightweight sweater with freedom for movement/without being tight, but if I wanted a roomy fit or the ability to wear a heavier sweater or sweatshirt underneath and still be able to comfortably button it I would have needed a small. The shoulders are cut broad — I have very broad shoulders and the XS surprisingly fits my shoulders well. This jacket may not be the greatest fit for you if you have very narrow shoulders, unless you are going for an oversized look.
