NOT COTTON!
I've been anxiously awaiting these data science themed ugly sweaters for two weeks and could not be more dissapointed. Geeksoutfit prices are quite high for print on-demand drop shipped clothes, but I was willing to pay for 100% cotton. Lo and behold their "Buttery soft fabric with plush" is 90% polyester. The website is incredibly misleading for which products are and are not actually cotton. The design itself is as pictured, but the images do not accurately show how shiny the material is in person.
