In terms of men's dressing, there are two things I see here that are not en vogue in Manila:

--It is perfectly all right here to wear rubber slippers as a substitute for casual shoes.
--I note a lot of men wearing "three-quarters" (pants that come down to mid-calf), which they often wear with sandals. Not to be confused with baggy, long shorts, though. In 1950s parlance, these are tight "pedal pushers", the kind you see in old Betty & Veronica comic books.
