My go-to shorts this summer
Size: 30, Color: Athens Mid Short - Medum Indigo
These are easily my favorite shorts this summer. The fit is super flattering and they have that classic Levi’s look that never goes out of style. The denim feels high quality and holds its shape without stretching out too much during the day. They’re comfortable once you break them in, and they pair well with pretty much anything. I also like that they’re not too short or too long—just the right length for everyday wear. Definitely worth it if you’re looking for a staple pair of denim shorts!

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!
