A shirt stay garter employs a releasable fastening clip for reducing a tendency for plastic and/or clam-type button clips to fail (e.g., come loose). Use of the improved fastener provides a center pin that keeps the shirt stay device from coming loose. The shirt stay garter may be embodied in a variety of forms including a stirrup style, a 4-strap style, and a Y-style, for example. The shirt stay garter may include a distal member adapted to be engaged with a support surface, a proximal member slidably coupled to the distal member, and a fastener attached to the proximal member. Notably, the fastener is adapted to engage the shirt tail and resists external forces acting thereagainst during extended periods of time.
