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!

good stretch
Size: 10 Long, Color: Dark Wash
Honestly, these are one of those surprisingly good basics—especially for the price. The biggest standout is the stretch. They’re really comfortable and move with you, so they don’t have that stiff “jeans” feeling. They hug your body in a flattering way without feeling too tight or restrictive, which makes them easy to wear all day. The mid-rise fit is also a sweet spot—not too low, not too high—so they’re super versatile with different tops. What I liked: Very stretchy and comfortable (almost feels like jeggings, but still looks like denim) Flattering skinny fit through the legs Easy everyday jeans—work, errands, going out Great value for the price What to know: Material is on the thinner side (more comfort than “structured denim”) They can lose shape slightly after a full day of wear Not the most durable long-term compared to higher-end denim Final thoughts: These are perfect if you want cute, comfortable, affordable jeans you can throw on with anything. Not premium denim, but for everyday wear—they definitely get the job done and are worth having in your rotation.
