Poor Quality
Size: 29, Color: Soundwave
This is my 4th pair of FP Barrels, and these felt poorly made. The holes for the button up fly were so small it was nearly impossible to button them. I’m going to see if I can stretch them out a bit. But better to buy from Free People directly!

Best dupe!
Size: 26, Color: Soundwave
Best dupe for the pricey barrel jeans. Washes and wears very well. Denim is soft.

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.
