I was perusing my local Nordstrom Rack recently, flipping through a rack of denim from a mix of brands, and my hand fell on what felt like 100% cotton jeans! Seemingly a rarity right now, as others have discussed. I checked the tag and yes they were!

Brand is "Sincerely Jules" (I think it was started by a lifestyle blogger - blog of the same name. I wasn't familiar until I looked it up.) and browsing her online store it looks like all her denim offerings are 100% cotton with some interesting shapes from the looks of it.

Will post a pic soon!
