I like to buy comfortable knit shirts of all kinds and have never liked the tags in the back but you deal with it and remove it. To me it is one of those things in life pretty much a small thing on my list of world problems.
Recently, my favorite shirts have become "Tagless" A novel idea, but they still have to put the tag somewhere so they sew it into the side seam. Now when I put my shirts on I have a scratchy waist until I remove the tag.
So, what's the diff???
