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.

Beautiful colorful dress
Size: XX-Large, Color: Hot Pink Leafy Floral Ditsy
This dress has beautiful, heavy fabric so it falls nicely but still has nice stretch. It is lightweight and comfortable. I’m 5’3” and it falls about mid-calf on me. I would definitely recommend this dress to others. I believe it fits true to size.

Simply Lovely and Versatile
Size: Large, Color: Navy
I bought this in navy for a family photo shoot. It's good quality, travels well (medium weight; no wrinkles) and works in all but really hot weather. I also wore it as a duster a few days later. As a result, I returned to purchase the emerald green.
