For semi-casual style, Uniqlo can be a reasonable option if you live in the UK (methink their online shopping actually ships anywhere in UK) Or if you live near SoHo in NYC, they have a flagship store on Broadway near Prince.
ye uniqlo clothing is quite gd, they have some nice cardigans there made from miriam wool or something which is better than normal wool and its like 2 for £25 i think. nice price for the stuff that ur getting.
I think Joot Designs pretty cool. Ya can check it at http://www.artisticpulse.com/shopdisplayproducts.asp?page=2&sppp=9
Zipia.net have some good looking cloths for male but there is a requirement of ordering over 500$ usd
they have such a nice sense of style hahaha hahaha people here should start dressing similar to them =]
hongkong clothes... not really i mean i think the one u said is the only one i know. that site has good clothes
i boughts some clothes on yesstyle and i was very dissapointed,i think its just isnt my style of clothes. thats the disadvantage of online shoping, you dont really know how it looks like untile you have wear it.
