Check your calendars and please note that summer is officially over. What this means is that you ladies are no longer allowed to wear ‘peasant’ skirts and those cheap azz chinese slippers.
Fellas should refrain from wearing flip flop sandals and messenger bags.
Several years ago I bought a pair of leather Gucci thong sandals because I wanted to ball out during my trip to Cancun. When I see guys in $5 supermarket thong sandals I always feel like an idiot for going the extra style mile.
