Tincati To keep shirttails where they belong—inside pants—Tincati sews in a tab that passes between the legs and buttons onto the shirt front. Every shirt comes with an extra collar and cuffs for when the originals wear out; they should be laundered every time the shirt is, so that the fabric continues to match. Two deep tucks down the center of the back make for an especially smooth fit.
