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!!

Good Quality
Size: 8, Color: Nautical Navy
These are really nice shorts. The fabric is nice quality. They do run a little large.

Love!
Size: 10, Color: Sailors Red
The quality is excellent. They are more of a faded red. I ordered a 10 worried they might be snug but that was a mistake. I should have stuck with my normal size 8. (I purchased an Amazon brand of this style that runs small and the size 10 feels more like an 8.) I love the length-not too short and not too long. They are sturdy cotton. There is not any stretch to the fabric. I’m giving them to a friend. I actually tried to shrink them by washing them in hot water and hot dryer but it didn’t make them fit me any better. Since they were already too big, I can’t really say if they shrunk by doing this. They weren’t huge on me before washing and seemed to fit the same way after. I tried wearing them all day and they seemed to loosen up even further. I was continuously pulling them up. I really feel like the sizing is accurate and you can be pretty confident of ordering your regular size. I’ve already reordered the size 8. I’ll update my review if there any issues with that size.

Unattractive but well made
Size: 4, Color: Sand
The style was unflattering overall. The shorts fit well in the waist, legs, and seat; they just made me look masculine which is not the look I was going for. For reference I am 5’7, 135#, and purchased a size 4 (which again, fit me well). I’m not sure if the issue was the length, or maybe they just down have a flattering cut - they are very boxy and hide any curves I have. 3 stars because the fit was good and they are well made. But just not attractive.
