I've enjoyed your posts MaFooFan but I think you need to focus on studying for the bar and less goofing around with a classic shirt.
Oxford cloth, button down, full cut, etc. all are part of a classic casual look to wear with khakis and a blazer, not an Italian suit. Why even bother BB with such a Frankenstein creation? I'm sure they were glad to take your money but the crew at 346 Madison is probably still laughing.
On the other hand, take a nice sea-island 120's and apply your design and you have something worth paying extra for, and leave BB out of the equation.
