This shirt was supposed to be "regular fit" but "mega obese" is more like it, absolutely nothing in common with the picture. Also the fabric was polyester-plastic-shiny, I don't believe that it's almost pure cotton.

Mens shirt
Size: 17"-17.5" Neck 36"-37" Sleeve, Color: Lavender Blue Check
It's a very well made shirt. I got it for my husband, he has to wear this kinda stuff for work. He actually loves this brand of shirt. Very comfortable. I actually got it on Amazon days or whatever it's called. So the price was cheaper than normal:)

Tried and true dress shirt but I love how the collar stays are actually sewn into the collar.
