I purchased two pairs of moxie FP jeans on Amazon both on sale. I love how different they are. The paint splatters are just the right amount in my opinion. I think the barrel leg is just wide enough without being obnoxious. I like an oversized look and these were the right price for me on Amazon. I love the rope waistband on these too

Not my style

Size: 27, Color: Snake Combo

Okay okay— so the fit good. I don’t like the buttons up the front instead of a zipper. The barrel is VERY barrel— I felt like an old timey cowboy about to get into a duel. Immediately returned for me. But the fabric and pattern were 10/10.

Quality Jeans

Size: 31, Color: Laser Daisy

They didn't fit. I returned them. They are heavy. Quality material. I might reorder in a bigger size.
