  • Publication number: 20240023638
    Abstract: New garment-fastening techniques are provided. In some embodiments, a new form of garment enhancement device is provided, including a waistband, wristband or other body-holding band, clothing-fastening band including a plurality of alignment- and grip-enhancing sub-elements located on or about an inward-facing side of the waistband, wristband or other body-holding band. In some such embodiments, the alignment- and grip-enhancing sub-elements are at least partially located with a channel. In some embodiments, the alignment- and grip-enhancing sub-elements are uniquely shaped and spaced in a pattern provided on or about such a band, which unique shape and spacing improves garment positioning during sleep, and provides a non-stick hold on a user's body. In some embodiments, such a pattern may also form a written message or indicator (e.g., product branding), viewable by a user.
