In hunting for more Worlds Within stuff I came across this picture of Hyun Bin and Song Hye Kyo, presumably promoting WW:
I can only appreciate their immense dedication to their craft - surely it is to indicate his character's vision issues that Hyun Bin dressed into a three-piece suit with a long t-shirt underneath and a thick, half-tied tie over a bare throat. And surely it's to convey her character's turmoil that Song Hye Kyo decided to look like a multi-colored baloon. Also, it is kind of them to inspire us to frugality by skimping on material where material should normally be - "who needs a collar?" asks Hyun Bin, "and a skirt that does not look cut-off" adds Hye Kyo. After all, we are in dire economic times.
Let me put it this way - any outfit that makes Song Hye Kyo look fat is one that has no business to exist. It's kind of Hyun Bin to dress like a drug-addled hobo who stole from a fancy store at night, in order to make Hye Kyo's horrific outfit pale into isignificance.
Honestly, if anyone could have pulled off something this horrific, the two of them would have. The fact that they can't, means no human has business wearing that.
ETA: On a dangerously-veering-into-pathetic territory, they are holding hands! Awwww.
