Not linen
These aren’t linen, these are microfiber shorts. Fabric feels very cheap.

True To Size
These shorts fit true to size and are so comfortable. They have a drawstring waist, so you can adjust them for the best fit and wide legs. They are 55% linen and 45% cotton so they keep you feeling cool. The classic colors go with nearly any other colors or designs, making them stretch your wardrobe potential and saving you money. They were extremely wrinkled upon arrival, so I used my fabric steamer, and within 5 min they looked perfect. I love these shorts and wear them all the time!

Cute 2-pack pair of shorts
Color: Black, White, Size: Medium, Color: Black, White, Size: Medium
Cute shorts that have pockets and fit true to size. I love that they come in a pack of two as well. The black ones are my favorite and I feel like the fabric is a little softer on the black pair. The white ones are a little thinner than I would like. I was wearing an olive green colored underwear underneath them in the pictures in my review and though you can’t see them much, I do feel like they were slightly visible. The white pair also had a lot of loose strings on them which made me think the quality might not be as good as with the black pair. They washed easily and I hung them up to dry them because they smelled kind of funny when they arrived.

Good value for 2 shorts
These come vacuum sealed and have crazy wrinkles... so be prepared to do some ironing. I ordered the Mediums as I am a 6-8. The black pair feels a bit smaller than the beige pair... with both feeling tighter than I like for comfort. The look nice on, but feel like it constricts my belly a bit too much. Overall a nice basic set of shorts, perhaps size up for a more comfortable fit.

Super soft and comfortable!
I haven't bought new underwear in forever. I used to wear thongs, but now find them incredibly uncomfortable. The last few times I've tried to buy new underwear, the sizing was either way off (I'm a medium, but gave up after having to return them for a large and then extra large) or the quality was horrible (two brands stretch waaaay out and they can fall down while wearing them (I have larger ass-ets, so they shouldn't start to slide down during use). I tried these after buying some bamboo pyjamas and I love them! They are incredibly soft, comfortable, and stretchy. I can use them all day, and they work well, whether I'm lounging on the couch or wearing them under my spandex shorts at the gym, they don't ride up or slide down. They are both comfortable and look sexy, while providing support in all the right places. I haven't had them too long, so I can't speak on the durability, but they appear to be of good quality and I plan to order more, this time without the band.
