Consider the local culture of destination
Sure, “Athleisure” may be hip stateside, but in countries like Japan or South Korea, not only is it perceived as sloppy—it’s also offensive. Same goes for wearing flip flops in Arab, Hindu and Buddhist countries, or skimpy clothing in the Middle East and North Africa. To avoid unwittingly causing offense, read up on the country to which you are visiting’s dress code. An oversized scarf of shawl is also a good investment for more culturally conservative countries.
