Per Bob Gramann:
I'm 6'2". Having a suit cut "a little long" is never a problem.

I'm 6'5". Had one made semi-custom and, in my opinion, Kokatat
dropped the ball by mis-locating the waist cinch (which keeps the
bottom half of the suit from dropping too low).

Extra body length is a Good Thing bc it allows one to draw the
knees up to the chest without running out of suit length.

But in a normal posture, something is needed to "keep the pants
up" so-to-speak. That's the waist cinch strap - analogous to a
belt.

Four inches lower, and it would work.

It irked me to pay all that line for a suit, even offer to pay
more to have the waist thing fixed, and have them say "sorry, we
don't do stuff like that."
