This specific undergarment design is characterized by the absence of fabric in the gusset area. The style maintains coverage around the hips and waist like conventional underwear, but features an open space where the crotch panel would typically be located. Examples of this type of garment are often found in lingerie, where they may be constructed from lace, silk, or other decorative materials.
The principal purpose of this design often revolves around convenience and sensuality. This design may offer practicality for situations requiring frequent access, eliminating the need to fully remove the undergarment. Historically, such garments have been associated with both practicality and expressions of intimacy.
