In one embodiment, the present invention contemplates a T-shaped stiffening device to prevent a trouser leg from becoming entangled between the foot and a shoe, particularly and open-back shoe, of a wearer. Accordingly, the device includes a stiffening device having a central stiffening member arranged between two opposing layers, one layer having an exterior face having an adhesive. One method of use includes locating an interior portion of a trouser leg, preferably near the hem-line, where stiffening is desired and arranging the device vertically starting at the hem-line at a rear portion of the interior portion of the trouser leg. Finally, adhering the device to the interior portion of the trouser leg using an adhesive provided on the device.
