Plackets are constructed with double layers to enhance the strength and durability of garment openings or slits. Given the frequent stress and movement experienced by plackets during garment wear and removal, the double layer mitigates fabric stretching, tearing, or fraying at the edges. Furthermore, a double-layered placket ensures a tidy and finished appearance, facilitates fastener attachment (e.g., buttons, zippers), and helps maintain the garment opening's shape over time.
