Nice design Size runs big
Size: 4, Color: Nautical Navy
The size 4 runs kinda big. It’s a very relaxed fit. I’m 5’8” 140 lbs and I need a belt to keep the size 4 up. Very nice fabric, great cut. I’m happy with them just didn’t expect them to be as baggy.

Stretch out, size down but love the shorts.
Size: 8, Color: Ocean Breeze
Love these shorts. My favorites ever. I always always wear a size 8 in shorts. The 8 fit initially, but stretched out so much, I didn’t have to unbutton them to get them out. I bought 3 colors. I finally bought one in a size 6. Perfect fit, even if they do stretch a little. Returning the unworn ones, and replacing with size 6.

Love these shorts.
Size: 4, Color: Jet Black
Five inch for a great mom fit. Cute button closures for the pockets on the back, nice deep pockets. It’s hard to see in the video because they are black but they are the comfiest shorts. True to size. I’m a size 3-4 and the 4 fits perfect…. Even after washing and drying.

Excellent quality!!!
Size: 10, Color: Ocean Breeze
Wow great quality!!! You get what you pay for that’s for sure!! The fabric is heavy-ish-indicative of quality fabric. Fit is spot on. I’m a barely size 10 (5’6” 160 lbs) and these shorts deliver!! The stretch is just perfect enough for comfort. Excited to wear these next summer!! Will watch for more sales so I can grab a couple more pairs. If you’re on the fence, get them!!
