Neutrino, I measure 37"-38" in the chest, depending on how you measure, and a Small Ashland fits me very well (an Epaulet Medium still has a bit of room for me). If an Epaulet Medium fits you very slim, you'd probably be able to wear either, but an Ashland Medium would have more breathing room. Hope that helps. Let me know if you have questions.
