  • No permanent vehicle modifications required for installation
  • Manufactured in-house at Active Autowerke€™s Miami, FL facility

Worthy
Size: Small, Color: Calypso Blue
I have to say, I seldom receive something thru Amazon that's 100% worthy! I wear F P & AE & these look just like the model! I usually wear a M, but knowing how fp sizing is, I got the S. Fits perfect with even a bit of room. Im 5'3", 127lbs, 27 waist. Definitely great with flats, but I'm not sure yet with any other than tennis shoes. The paint splatter on mine are less than picture....no complaint here. They have a bit of stretch, I like real jeans, so I can live with it. They are soft & actually made well. Only downside to this order, Amazon made me purchased over what I wanted to, to get it by promise date, never happen & getting very common with that trick, not appreciated, so beware you may not get them on promise date

Way to short, cute, but short
Size: Medium, Color: Green Multi Combo
I would give these a 5 star but they were 3 inches to short. So cute though. Will try a large to see if that makes a difference. Im 5'7" 147lbs. Everything else was a great fit but serious highwaters

I am short and these jeans are like normal jeans for me. 5’1” and size small ordered. I love these jeans!! They are baggy and have a good stretch. They have a cute drawstring as well as a belt. Plenty of pockets. Comfy and soft denim plus zippers are good too. Recommended!!
