Ok so I stumbled on to these looking for something completely different, but I’m so glad I did! These are cotton with 3% elastane for som stretch. I really like this fabric, it’s a stronger poplin feel, mid-weight. They do run a touch loose, so if you are in between sizes, you could size down! I like these for when I don’t want denim or activewear. The brown is more true here than the listing, FYI.
