or just moved on from the good ol' days when hedi was running tings? those cps are about as sleek/pointy as a derby can get without venturing into winkle picker territory (again, see hedi circa 2003 and,uh, ever since).
none of this is rocket science, a black suit can look extremely striking but you have to be able to carry it off. why else was it the signature garment for raf simons, hedi slimane, yamamoto, etc. whether it's 'acceptable' or not depends on your business.
not sure there is a consensus... they vary from season to season. TTS seems to work for a lot of people but i'm a large 48 and took a 46. the pattern seems very accommodating though- a friend who is at least a size smaller tried mine and looked fine in it. the key thing for the modern version is that you must have a slim waist, it has a strong taper as the picture on this page shows.
