Surprised at the very good quality of this vest.  I'm 5'9" and a 44 reg.  Using the Amazon size chart. I ordered the XL and it fit me perfectly,  Bottom of vest covers shirt and belt area as it should for formal or morning wear.  I'll be using it with a "Stroller" suit for a wedding and it looks great.  Wish they had this same vest in a tan or buff color.
