Full Coverage
Size: Large, Color: B2207sp
They're nice and light, super stretchy, and not too tight around the edges. Im a size 14 and got a large amd They're a smidge tight, but I think if I would get an xl theyd fit perfectly, They're still comfy as is. One stipulation I had is I wanted them to cover my whole butt cheeks, nothing cutsie short cut, not for this. They cover my entire booty cheeks and stay there pretty well. Oh and also no camel toe! Id buy them again and would recommend them to anyone.

Make sure you size up!!
Size: 4X-Large, Color: B004
Allllllmost 5 stars if the sizing was correct. I’ve been on the hunt for a decent fitting pair of women’s boxer briefs. I would say these are more so boyshorts. That being said, I wanted something loose for sleeping in so I got TWO sizes up. I normally go for a 2x and got a 4x and they’re perfect fitting. So, you didn’t get what I was looking for but did end up with some decent fitting undies. So I can’t complain too much. Just not the boxer briefs I was hoping for. Super stretchy and soft. Comfortable for sleeping in.

Really comfortable, good fit
Size: 6X-Large, Color: 5 Pack(black,black,blue,blue,light Coffee)
These are very lightweight and comfortable. The material stretches freely and doesn't bind up anywhere. If you go by the size guide, they should fit perfectly neither too loose nor too tight. Would definitely recommend.

These don't work for me...
Size: Medium, Color: B005
First the good... I like the material; it's very soft, light, and stretchy. I also like the colors, but that's all I like about these boyshort panties. My main goal for panties is to have them NOT ride up into my butt crack leaving the bottoms of my butt hanging out. It's probably comfortable for some, but it drives me nuts to feel this constant need to pull them out of my butt crack and down over my butt cheeks. If I wanted my butt hanging out I'd buy thongs, LOL. The part I really don't understand, is why they make the front and the back the same width/length. I mean clearly more material would be needed in the back to fit around two round humps, right? I mean I guess unless you have what I call a pancake butt, I don't see why there shouldn't be more material on the backside of the underwear. Why is it so dang difficult to find underwear in this style to fit up over butt cheeks? If I pull them down enough to cover the bottoms of my cheeks then the waistband is sitting right at the top of my crack which is extremely annoying (then I feel this constant need to pull them up!) especially when the front is long enough to go up to my belly button!! Who are they making these underwear for??? Ladies with FLAT butts apparently. For reference, I'm 5'5" 130 lbs, hips 37", waist 27", athletic build, as in lean but with muscular glutes & quads from speed skating. Not only are they not made big enough to go up over my rump while still keeping my cheek bottoms from hanging out, but they're too long in the front cause they constantly roll up in the front. I've even tried turning them around, even though they seem to be exactly the same front to back, and they fit exactly the same, no surprise there. I may just be out of luck finding comfy boyshort panties that actually fit the way I want them to. :/
