The Slick Stitch is an item that can be applied to attire to enhance the bonus the attire gives. When used on either Il Cugino or La Cugina attire, they may increase the bonus the attire provides, up to 50%.
How to Use Edit
Slick Stitches can currently be acquired from the Airport for 1 Boarding Pass. To use, go to the attire upgrade screen and click "Tailor" on the scroll down menu. The tailoring will most likely fail, but if it succeeds, the bonus is enhanced anywhere between 5 and 50% (in multiples of 5). The enhancement can only go up - it will never decrease.
