Has anyone noticed any weird changes in the neck size of BB non-iron dress shirts. I have a lot of them, but the last 5 or so that I purchase were in the usual neck size of 15, and they seem to be a little large. Three or four weeks ago, a SA at BB had measured and told me I was 15.25, but these 15 dress shirts are a little big. The odd thing is that the shirts I picked up earlier this year are fine and fit perfectly around the neck. Plus, my shirts from other brands like Charles Tyrwhitt are fine at 15 neck size. I guess it's possible that I lost weight, but that's a pretty drastic drop for three to five weeks.
