Best Jeans Ever!

Absolutely love these jeans! I just bought two more pairs in green and rose? Had to go directly to Free People website because Amazon was sold out…I get so many compliments, and I’m 74🤣‼️😉

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.
