Internet shopping in Hong Kong still has a ways to go. Apart from YesStyle.com, which is a firm Sassy favourite for its huge choice and beautiful packaging (it feels a little like sending yourself a gift in the mail!), there aren't a huge number of other options.
We stumbled across Korean brand Smoky Alice, and just love their pared-down and simple approach to styling and the selection of wearable basics. Each piece has just enough of a twist to elevate it to something special. In particular I'm wanting the long cotton skirt above - paired with a simple tank I think it would be great for daytime around town. Confusingly the site is in English, but then switches to Korean as soon as you try to find out where they ship!
