japanese street style is really varied, but i believe it is so because the young people, and perhaps fashion-inclined older ones in japan, are more daring in their choices pertaining to fashion. almost everyone is a fashionista, so perhaps people are constantly aware of what others are wearing, fashion trends, methods of styling etc. even though two people might possess the same 'style', the main differences arise thru accessorising (quirky shoes, bags, watches etc.) and the carrying off of their selected outfits. fashion is serious business in japan..
in singapore, though the fashion scene is heating up, it is still rather passive generally. problem is, people in singapore don't bother to accessorise. sometimes, climate is not an excuse. (of course, sensibility has to be in place.) u can be wearing a simple outfit, but the difference is in the styling of the entire look.
HK street style may be heavily-influenced by japanese hiphop/skater styles, but at least the shopping in HK is way better than what singapore has to offer. sad state of affairs though. o_O that said, i don't condone the blind following of trends by hongkongers, cos i still reckon style is the main factor, not brands. (and yes, BAPE is rather overrated isn't it? no offense to BAPE fans!) afterall, if one doesn't have the confidence to carry off an outfit, what good would a balenciaga weekender bag be? (or for that matter, all the LVs and guccisima hobos in the world) somehow, if u have the panache and eye for good (not necessarily expensive) stuff, u'd look like a million bucks even though your outfit only costs $50. =)
