Just found out that the custom shop I work for can do them. Had a few sales and decided to get my first suit.  We cater to a conservative business crowd, lots of slightly structured roped shoulders and side vents, but when I asked for a very natural shoulder and a 3/2 roll he suggested I go for an undarted model "just like Brooks" (where he started his career).

So I am getting a sack suit in a charcoal herringbone flannel with a blue windowpane. Three patch, side vents, side adjusters on the trou. Pics to come in 5 week.
