where in Denver to get pea coat altered

[kpp80202]

I lost about 20 pounds and was wondering whether a Schott pea coat (that I love) in sz 42 can be "tailored" down to a sz 40. If so, anyone know a good tailor in Denver who works on things like this? I have used Cherry Creek tailors in the past for suits, and had good results, but this a bit different.

Also, can suits be tailored down from 42's to 40's? It seems like a lot to me, but I'm a newbie at this.
