Question for those with experience with the Brooks Brother's OCBD: I wear the ESF OCBD in a 14.5 / 32 (the USA made ones). It fits well but is quite fitted, namely I can't fit an undershirt underneath. I would like to be able to wear an undershirt under the OCBD--would I be better off sizing up to a 15 in ESF or getting a Slim Fit in 14.5 for a little extra room in the body of the shirt?
I remember the website having more comprehensive shirt measurements before the re-do--which I would have consulted--but I couldn't find those when I looked.
Sounds too well fitted.
The shirts, esp. the OCBDs, shrink over their (otherwise long) lifetime. I launder cold, hang dry, and still they get smaller--more in the neck and sleeve length than chest. You can't be too fussy about the fit of your shirts without buying 50 new ones every year. What fits perfectly now, won't in three years, etc. When those shirt deals roll around, I will experiment and order different sizes. I'm usually a 16 or 16.5 in the OCBD but ordered a few 17s this year, because the oldest 16.5s need the button moved to wear a tie. If they are too big, maybe they won't be in a few years.
Button up your shirt. Can you get a finger or two in there? Is it comfortable? If so, don't size up in the neck. I'd try Slim Fit if the neck on the ESF is loose and you need more around the tits. If the neck is tight, size up that way for sure. Even if you are not going to wear a tie, the shirt is not going to fit so right around the neck if it won't close comfortably. The shirt should be smooth and flat between the top button and the top of the shoulders. All the time I see pulling as people are squeezing into too-small shirts they couldn't possibly button at the neck (and are cut too small for the top of their body).
Changing the sleeve length probably won't do anything to chest circumference.
