Jackets can either be non-vented, side vented, or center vented. Side vents, long used in Europe, are gaining popularity, but the majority of our clothing will be non vented. We find it hangs better and is more flattering. With your arms at your sides, the back of your jacket should lie perfectly flat-there should be no wrinkles or waves in the back or collar. Your pants should hang freely, breaking just above the shoe.
Shirt sizes change.
Let us measure your collar if you have any questions about your shirt size. Always leave room for some shrinkage, even with expensive shirts. You should be able to slide two fingers between the collar and the neck and you should be able to comfortably button the shirt. The shirt sleeve may extend just a little bit past your jacket. Never wear a button down shirt with a double-breasted suit.
