I recently picked up this oxford shirt from Gant Rugger: http://us.gant.com/r1-j-oxford-awning-stripe-ez-obd
I'm 6'4'', 220lbs. (I have big legs). Despite loving the brand, most of the Gant Rugger stuff is cut rather slim and short, making my selection a somewhat more limited. I was looking for an oxford shirt that I could just wear casually and found this.
The size is L. The shirt is a bit more billowy than what I'm used to, but I'm afraid if I size down...
