I have a problem with certain dress shirts where the fabric above the top button tends to roll over after a few washings, making it difficult to get the tie to sit correctly. My shirts are all either Brooks Brothers or Polo, this has never happened to any of the Polo shirts, even those years old, but happens with almost all of the Brooks. I can't tell a difference in the construction that would prevent this on one vs. the other. When I had a Brooks MTM last year, the salesman specified something where an extra stitch goes around the top inside of the collar which I think is designed to make it stand up straighter. So far that shirt has not had this issue. Any advice on avoiding this with future shirts either MTM or RTW?
