I have read about the TM Lewin shirts on this forum and want to give them a try. Their website does not show any shirts currently available in my size-17.5, 35/36. I e-mailed them to inquire when my size would be available but received no response. I want to get a true RTW british spread collar shirt, not the american version of a spread collar. I have recently bought some RL 'regent' series shirts, which work, but I might as well get the real thing such as Lewin. Am I out of luck on size? Do Lewin shirts fit smaller, larger, or the same as US shirts? Is the 'Prince of Wales' series what I'm looking for?
