Three-roll-two: delineated the sartorial flair and exuberance

Presumably, you have seen some classic jackets with four buttons and three buttons as well, which are meant to fasten the top buttons; hence, obviously, they have a front opening that is relatively high and short. Thereafter, the influence of sartorial evolution changed the perspective of having a higher button stance and a short front open on a suit jacket, blazer, and sports coat.

Therefore, the visual impact of the lower button stance creates an elongated, beautiful V-shape on the front, which is quite familiar among men who were sartorially inclined before then. Though we have the option to choose a three-button suit, conversely, the three-roll-two is distinctive and has sartorial flair.

However, the style of the three-roll-two jacket/coat is essentially intimate with the Ivy League style, which in essence is a single-breasted suit jacket/sport coat designed with three buttons and functional buttonholes on the front flaps of the suit jacket/coat. Besides,  the appellation of three-roll-two is defined by the top buttoning point, which is placed beneath the lapel roll, so it's preferably unbuttoned always.

The lapel roll is an element of daintiness on the jacket, which involves intricate handwork on the canvas to create a nice concave effect beneath the lapel towards the buttoning point (lapel roll); hence, it is also a manifestation of craftsmanship.

Apparently, the three-roll-two suit jacket/sport coat enunciates personal style and exuberance; moreover, it delineates the essence of craftsmanship and sartorial flair.
