Dear fellow Fedora lounge members, I have a question, for which I wasn't able to find a proper sartorial answer in my beloved Apparel Arts or Esquire drawings When wearing a classic double breasted dinner jacket during autumn/winter time, what is the proper waist covering? I dislike the cummerbund, and otherwise have a classic 1930 barathea waistcoat but can I wear it with a double breasted suit? Or some of you would say that the double breasted is meant to remain buttoned at all times, and that the question is irrelevant? And so nothing under the jacket? Waiting for your suggestions/reactions... Thanks for your pieces of advice.
