Thompson slim-fit flex wrinkle-free shirt in mini gingham

Great shirt... Love the collar... though NOT comfortable. The shirt is slim-fit. I personally don't like slim-fitting shirts as dress shirts, especially since these would be "daily-driver" shirts for work. Need a comfortable fit. I tried one size larger, and holy cow... WAY too large (long in sleeves & too baggy everywhere else). Very disappointed, because I seek a shirt of this caliber, but one that isn't slim-fit. I'm not going to a fashion show, nor a wedding, nor a photo-shoot. I just need a shirt for work that I can breathe within. Note: I am 5'10", 145lbs and purchased a Small and then a Medium during my trial/test. I am accustomed to simply choosing a the next size up when I do see a slim-fit as the only option (which in itself is very rare) and that has always worked with other brands. This brand however doesn't work in that manner. :( Rico
