Guallaberas is a traditional Cuban dress shirt. Being a Cuban myself, and lived in Miami, FL for many years, I can tell you something or the other of typical Cuban attire. If you were to walk in the park in Miami, and happen to see the folks at the domino table, you will notice they have on these types of shirts. 

I hope you all enjoy!
Installment notes: unzip the bitmap files into the "skins" folder in your Rockstar Games \ Vice city directory.
