I'm sure that this question has been answered before, but, how much can pants safely be let out? I'm looking at a Zegna suit in a plain charcoal that will make a good staple, but the pants are a little tight. The jacket fits me perfectly, but the pants might need to be let out by as much as 1". Will this affect the cut (or whatever the term is) of the pants significantly, or is 1" not that big of a deal. Normally, I would just move on, but I really like the way the coat fits me and it's hard to find plain charcoal with any kind of a discount (Saks is giving me 20% off).
