The sizes run small, and also vary from jacket to jacket.  One of the XL jackets fit me, another XL was too small.  I finally settled for a 2XL jacket in camel color which seemed the same size as an XL in the khaki color.  I liked the camel color best (just a personal preference).  The jacket sleeves are a bit long.  The blazer is advertised as 3/4 sleeve, but the sleeves on the 2XL are a bit longer than that coming to an inch or two short of my wrist.  One sleeve is about an inch longer than the other.  But, this is an inexpensive garment, and the color works well with a pair of pants I own, so I'll keep it.
