Good call @FrankCowperwood - I'd agree. We're doing a lot of New Bond Collars and Artisans on flannel orders recently.
Any buttondown collar will be made with light lining - so just a thin piece of interlining sitting inside the collar. If you choose a non-buttondown like the PT, Fashion Spread, or Artisan then we'll do "Ladies Light Fusing," which gives a soft collar that still keeps it shape. We do this by default.
Ladies Love Light Lining would be a great name for a #menswear hip-hop group. (Just gotta make sure James Todd Smith isn't in a litigious mood.)
Call me old fashioned but I love the Individualized button down collar for a casual shirt. I got three Fall 2016 shirts done with this collar. This being said, I have the Artisan with LLLining in some shirts and it's an incredible collar if you either (1) have a dressy fabric, or (2) have any fabric with a medium-scale pattern, like the Rezzo Brushed Twills, the Rapallo/Taviano Flannels, the Sovereign Melange Ginghams, or the Saranac Brushed Twills. My vote is always for a big, lightly lined/unlined button down collar, but substantial spread/non-BD collars like the Artisan look incredible with some good pattern in them.
