Thanks for looking at my listing.  I'm selling my 16 Duchamp shirts that I've bought over the years due to frankly gaining too much weight.  : (  All were purchased by me from Duchamp and had the sleeves shortened a bit from the standard Duchamp length.  Please look at the measurements for each shirt (if interested in more than one) and compare those measurements with perhaps a shirt you already have that fits as desired.  If you have any questions, please let me know. Thank you.  

Collar size:  18 inches
Pit to Pit measurement measuring the width of the shirt:  25 1/2 inches
Length measurement measuring from top of color to bottom of shirt in the back:  33 3/4 inches
Right sleeve length:  24 3/4 inches
Left sleeve length:  24 1/4 inches
