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.

made well
Fit Type: Regular, Size: Large, Color: Iced Light Wash
I couldn't get this in my size (medium) so I ordered large. it's a little large in the shoulders, but it still looks good. it is a well made, substantial jacket. I love it!

Lovely fabric
Size: X-Large, Color: Black Ivory Geometric
Very nice dress that can be dressy or casual
Substantial fabric that’s not see through and doesn’t wrinkle
Great value
Fit is flattering
I know it good when my husband notices and says it’s nice!
Update … I liked the dress so much I ordered 2 more in different colors
Only caveat is the pink floral one is actually red
The background is definitely not pink
