Not only do these feel good, my husband can’t keep his hands off me. They fit so good and are soft. I change into these to sleep but also just use them as shorts to wear around the house. They’re comfortable and don’t slide around. I got a size small and I’m 100lbs.

Finally!
Size: X-Large, Color: All Black D (5-pack)
Finally, comfortable underwear that don’t end up giving me a wedgie. I have a round booty and most cuts of underwear end up shifting as I walk and sit. The hem of the underwear comes right under my cheeks and the lightweight material ensures there’s no panty line and no shifting to where I don’t want them! I’m definitely purchasing more.

They’re fantastic!!!!
Size: X-Large, Color: Multicoloured E-(5-pack)
My clothing size is 16/18 and XL. Even though Amazon suggested a size XXL, I ordered my normal XL and they fit perfectly. The fabric for this style is 92% bamboo viscose and is amazingly soft and almost silky feeling. I had ordered a different boy short in this brand but they were 80% bamboo viscose and the fabric was significantly heavier. I returned those and ordered these.

Boy have I bought A Lot of Underwear
Size: Medium, Color: Black,navy,melange,london Blue,burgandy
These are my favorite boyshorts so far. The little stripes kill me, they're so cute. I am now an expert on boyshorts. You should know, I always buy the color packs with boyshorts with a make-up that look like static on the tv. Not sure how else to describe that but they tend to be the same across the board and I think they're super cute, personally. The solid colors may be a different story. SO-Here's what I've learned: They're all basically the same, minus the material and how you like them to fit. You want to look at what the exact material content is. Do you like super soft, almost gauzy and you're not concerned with possibly snagging them? Then you'll want to find boyshorts with a high percentage of polyamide. These are not them. These are about 50/50 polyamide and polyester, which is firmer and has less stretch. Not gonna snag them in regualr situations. Still lots of stretch, though. Just more support and more excercisey material feel. But, there is enough polyamide in them to still feel soft. I prefer less plush and more support. There is a dash of spandex in there and that's good to accommodate many bodies and to hold their shape over time. I know some gals are looking for a softer, stretchier, plushy boyshort. They're easy to find. Look at the material listed. Okay, about sizing: These are stretchy. Not SUPER stretchy, like the gauzier underwear, but stretchy, and you'll fit in most of the sizes. The fit will just be different, obviously. I'm a large in regular pants typically. Size 12. Ten in a good month. I'm 48, 5'5 and 165 pounds. I've got a booty, but not super-duper bangin. Just big. Anyways, I've gotten my "true" size (L), sized up (XL) and sized down (M). Sizing up (XL) is too "poochy" feeling and just mildy wads up around where my legs meet my bits. Comfortable, and stay on but saggy feeling to me. The true-to-size, size large, are less "waddy" and fit fine! Loose enough to almost forget they're on. I've sized down to medium, and that's where my preference is. They fit like I have work out shorts on, just very short ones. More support but don't look ridiculous. I don't look like a sausage in them. Size small would be that on me-the sausage shorts. I mean, I'm wearing these around the house in the summer so I don't have to crank my A/C., and for bed. They aren't gonna be seen my many. Either way these are going to roll up (super skinny gals without thigh gap...do boyshorts roll up on you too? Always wondered that) but the smaller size on me seems to roll less, and that roll doesn't bother me. A roll is different from a "wad". Actually I wouldn't even call it a roll, I'd call it a "fold over". Ha ha I hope this helps and you understand my lingo. FYI I have found personally that most of these brands are the same exact thing from China, packaged and branded differently. The material is the big factor. But these are the only ones I've found with little pinstripes. CUUUTE. Good luck out there!
