Have you washed the shirt yet? Â Chan told me (via email) that regular laundering shrinks their collar about .25", so if you think it's too tight pre-washed, go ahead and ask for +.25". Â Don't forget that you can also ask for 1/8" if you think .25" is too much. How's the sleeve length? Â Looks just right in the picture, however I like mine a bit longer. Â You may consider adding another .5". Like I mentioned before, go with -2.0" or -2.5" for the shoulder measurement. The body measurements are your preference. Â Wear it around for a couple of days and see how you like the fit.
I've washed the shirt already, and the collar is okay, but a little on the tighter side, so maybe increasing it is a good idea. The sleeve length is perfect when my arms are straight, but I also like the sleeves a little longer so that there isn't as much pull when my arms are bent. I already ordered my second Chan shirt, and asked for the sleeves to be lengthened by .5. I think I am going to reduce the shoulder measurement on the next shirt by about 2". Now that I take a good look at it, the shoulders do seem very big (maybe that was just wishful thinking on my part).
As for the body measurements, I'm pretty happy with them. All in all, this shirt fits me better than any RTW shirt that I own in spite of all the problems with it. Thanks for all the help.
