Do you need a suit or a sport jacket ensemble? Arcteryx has their Veilance line which includes a covert sport jacket, Only down side is that it is only available in a S M L Xl sizing with no tall option.
There are a couple threads here that cover suits and dress clothes pretty well- Let me see if I can find them. They are from a couple years back.
Sport coat, pants tir...etc
Just been eating trough good dress suits and seems not doing well after some events.
