Cute
Size: 29, Color: Deep End
They were a little on the shorter side. Still cute and still will be worn.

Exactly as FP describes
Size: 27, Color: Deep End
Quality denim with the classic FP barrel or horseshoe leg. These are deep, dark blue rigid denim with a button fly. Hits at the ankle for me, but if you are shorter than 5'9" you may a get full length fit from these. I own these jeans in multiple colors and these are another FP win for me.

Perfect lightweight denim for summer in Florida!
Size: Large, Color: Union Blue, Size: Large, Color: Union Blue
LOVE EM. Insanely comfortable and lightweight quality denim with a kiss of stretch (perfect for summer). I pair them with tees, cropped tops, tanks or button up shirts. They’re adorable with sandals, sneaks, flats or flops. I went through about 5 pairs of jeans from different stores looking for the perfect combo of lightweight, comfy and stylish; these fit the bill. The distressed accents (a few rips and paint flecks) add interest without being over the top. The attached belt is such an adorable accent. Love love love these and will likely buy a second pair. True to size.

Super comfy, roomy, great quality!
Size: Medium, Color: Calypso Blue
These are so cute! They fit nicely, actually run a bit big but that’s probably intentional. I’m short, just a little over 5 feet tall and they are the perfect length for me. I got a medium, i normally wear some mediums and some larges. They are lightweight denim and great quality!

Sturdy fabric, well made.
Size: X-Large, Color: Royal Blue
I LOVE these pants!!! Who buys pants online??? I NEVER do, but I took the chance band I absolutely adore them!! I’m 5”10’ 200lbs and they are so super comfy and look fabulous on me too. (If I do say so myself) Wore them to the baseball game and got three compliments. Might order another pair? Seriously, they are well constructed. Good solid material with just enough stretch. The pockets are actual Pockets. I seriously love them.
