Favorite Summer Shorts worn on repeat
Size: 31, Color: Luxor Heat - Light Indigo
These are my favorite shorts for summer. I have several pairs that I wear on repeat because they’re comfortable, flattering, and hold up really well. I ordered a size up from what I already have since I’m postpartum, but I ended up not needing it—my original size still fits me best. So I did return these, but only because of sizing, not the product itself. I do suggest sizing up 1 size from your normal size. I usually wear a 29 and have these in a size 30 and they fit great. They are a true jean material and not strechy. Highly recommend these if you’re looking for a reliable, go-to pair of denim shorts.

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.
