Going from odd to even sport coat size

[jussumguy]

Basically, a size 37 sport coat from Brooks Brothers fits me perfectly. Unfortunately, not many 37s to be had, so would you go down a size, or up? The 38s were slightly too wide at the shoulders, although probably passable.

Try them on.

Try different brands.

They ain't all the same. Most of us have different sizes from different brands.
