I got an early WvG before-dinner shirt and they have long since adjusted the fit, so I don't think I could compare the two fits in detail that accurately. Taking the same size in both is still the best bet, taking a quick look at the measurements. In general my impression is that WvG is going more for a skinny BoO fit and Epaulet's is more athletic. I enjoy wearing my Epaulet and Ashland shirts more. They sit much better on your shoulders.
