A garment includes a first side, possibly corresponding to a user's front. The first side includes left and right portions that each have a free mating edge. Fastener elements are attached to or formed in each of the right and left portions of the garment. One of the two portions includes a two layer placket. Some of the fastener elements include a portion on the outer layer of the two layer placket. At least one interstitial fastener element is positioned only on the inner layer and is between two other fastener elements that include a portion on the outer layer. The at least one interstitial fastener element may be positioned at a wearer's chest or waist region to minimize or eliminate gapping of the shirt in areas of larger girth.
