Abstract: An imperceptible undergarment fabricated from a transparent material or a skin tone colored material. The clandestine material creates an illusion whereby the undergarment is not easily visible to onlookers. This discretionary look may be beneficial when a wearer is wearing low cut or minimal outer garments that do not fully cover the undergarment. Numerous straps, fasteners, and adjustment clasps provide myriad options for the wearer to adjust the imperceptible undergarment for a proper fit, and to further conceal the undergarment. The imperceptible undergarment may also be fabricated from a clear plastic or breathable fabric that is efficacious in dissipating heat and providing outlets for sweat in areas of high heat generation, such as the breast, the buttocks, and the groin area. A plurality of apertures, thin webbings, or pin holes strategically positioned throughout the imperceptible undergarment provides release points for the heat and sweat.
