Finally brought my coat to the tailor. The sides and collar were taken in. Here's a quick pic, but I'm planning on wearing it mainly with grey flannels. The way Luxire made it means I can wear it as a 6x2 or 6x1, depending on how 80s I feel.
Chocolate brown wool or cashmere ties, possibly with a stripe or larger medallions, but the texture alone should be enough. Make sure your shirts have some texture as well, such as end on end or a dressier chambray.
