I own both the navy donegal and the taupe herringbone flecked wool raglan from the current season and sized down one in both of them, as advised by Drake's. I'm happy with the fit and though tts didn't look 'bad', it was too big for my taste. However, shoulders run surprisingly narrow in my opinion, so if you're into weightlifting or naturally very broad-shouldered, you might want to consider going tts.I’m interested in this coat as well, but should I go true to size or downsize one size?
