Does anyone know whether the horizontal creases at the buttons on some waistcoats are caused by having a garment with a floating canvas? I think I have mostly observed these on expensive suits. This is probably an eccentric preference, but I really like those creases. Maybe because, especially on a taller person, any horizontal line breaks up the length of the overall figure. Which is probably why I also like tie-clips. I haven't been able to find a photograph to illustrate this, in case it is not clear, but I will try to add one later.
