Cute - SIZE UP
Size: 33, Color: Luxor Heat - Light Indigo
these are super cute and look very flattering but they run SMALL. I used to wear 32s in Levi’s but lost 30 pounds this year so I ordered a size down and they didn’t fit at ALL. I reordered a size 33 and they still fit tighter. My Levi jeans in a 32 barely stay on me anymore but these are snug in a 33. They’re still super cute and comfy, guess it gives me room to size down into them for awhile lol

I love these!
Size: 30, Color: Athens Mid Short - Medum Indigo
Wow! I got these for$20! They fit just like the 501 pants to me. . The only thing I'd change is s little less fraying on the front but other than that these are a broken in lived in look for $20!

Wish the sizing was more accurate, but still cute!
Size: 33, Color: Luxor Heat - Light Indigo
These shorts are super cute! I really love the color and style, but the sizing is WAY off. I typically wear anywhere from a 12-14 in jeans. After looking at reviews, I sized up to order what I thought would fit like a 16. Unfortunately they are pretty snug. I am hoping after a few wears they will loosen overtime. I would size up two sizes if you are a curvy girl like me! They do not have much stretch to them, but good quality denim.

Perfect shorts!
Size: 30, Color: Athens Mid Short - Medum Indigo, Size: 30, Color: Athens Mid Short - Medum Indigo
I was worried these shorts wouldn’t cover enough of the butt area or that I wasn’t thin enough to wear them especially since most of the reviews are from thinner people. but OMG, they’re perfect. I’m 5 4, 152 Lbs and size 30 is absolutely perfect. Size 29 would be small for me.

Cute distressed shorts but size up!
Size: 30, Color: Athens Mid Short - Medum Indigo, Size: 30, Color: Athens Mid Short - Medum Indigo
Love these shorts! These Levi’s run small. I usually wear a 28 and ordered a 30 because that’s what was available. I’m 5’1”, 135 lbs for reference. They’re distressed and shorter in front which are perfect for us short gals.
