Great shirt! Great price!
Size: 17"-17.5" Neck 34"-35" Sleeve, Color: Medium Blue
These shirts are listed for sale on Amazon with the title "Unlisted by Kenneth Cole men's Slim Fit." To me these shirts aren't "Slim Fit." I have purchased "Slim Fit" shirts in the past from other manufacturers and they were always too tight on me. I'm 6ft and 185 lbs. To me these shirts are more a standard fit and they fit me perfectly. They are made with a combination of cotton and polyester which means they resist wrinkling. And for about $20 each they are a great deal! Kenneth Cole also sells their "Unlisted by Kenneth Cole men's Regular Fit" on Amazon. These shirts should be called "Big and Tall" or "Full Size" fit. This is the first shirt I ordered, and they were too big on me. They are mostly for chubby or muscular men.

The world's most perfect dress pants
I have purchased several of these pairs of pants over the last few years at my job. I wear these pants every shift. They were great. They fit perfect and don't wrinkle or need ironed, that's a huge plus. I work 12 hour shifts in a hospital in a non medical role. So, these are dress pants, not work pants but they wear really well and do not show wear. I have worn other brands that have come apart. These are top of the line and the only pants I wear at my job. They are not not at all hot to wear either. Please, try a pair and I hope you love them.
