Coming to Korea this summer, I didn't have any idea what to expect with regard to fashion. I figured with my Phillies hat, polo shirts, and khaki shorts my clothes would broadcast "American" even more loudly than my skin.
In this I was somewhat mistaken. Korean fashion is a lot more complicated than I'm capable of understanding, but I see lots of polo shirts and not a few pairs of cargo shorts.
The big surprise comes with regard to the Phillies hat. In Korea, Major League Baseball hats are in style big time, especially among men but also among women.
The most popular teams are (expectedly) the Red Sox and the Yankees, followed by (unexpectedly) the Detroit Tigers and maybe the Pittsburgh Pirates. I don't think the people wearing the hats generally know anything about the teams, and so I suspect that the cool script "D" on the Tigers hat explains its prevalence.
I have only seen a Phillies hat twice. Perhaps when they win the World Series again this year, I will be able to welcome many Korean friends onto the bandwagon.
