I have a question for you. I have a navy flannel sports-coat which belonged to my grandfather and dates presumably from the end of the sixties. The manifacture is extraordinary and the material is lovely: 3 buttons with rolled lapel, angled pockets and everything hand sewn (it is a bespoke garment). However, the lapels have the hideous 70-ish funky shape; they have nice proportions but the notch is awkwardly acute-angled. I know that's something nobody would notice, but it really gets on my nerves. I thought that a good fix would be “squaring out” the notch angle by cutting a triangle from the collar piece. Here's what I mean: The white part should be cut out and a new edge should be finished, so that the notch would then carry a decent angle. Have you ever had experience with similar alterations? Do you think it is doable?
