A few months ago I saw some blog entries (can't remember which blog) chronicling the author's experience bespeaking a three-piece suit in Spain (I believe). The tailor included buttons to secure the vest to the trouser top, thereby preventing the dreaded shirt-revealing gap. This seems like a very good idea to me. I have a three-piece that allows some shirt to sneak through over the course of the day and I was thinking of having buttons added to prevent that. Has anyone done this? How did it work? How many buttons are used and where are they placed? Do either the trousers or vest need to be cut to specifically accommodate this bit of engineering?
