I recently visited Hong Kong and did my ritual visit to GOD (Goods of Desire) and Muji. GOD is a quirky cross between Ikea, Top Shop mixed in with retro Shanghainese style. There is always something to surprise you. http://www.goodsofdesire.com/

At Muji, the budget Japanese homewares and fashion store, they have a clothing range called Labo: clean lines, basic styles, muted colours – more expensive than their standard fare but definitely worth checking out.
