there are also quite a few fancy-pants kids clothing shops in shatin new town plaza.
personally, i could never justify spending $200+ on a kid's t-shirt. they out grow them so quickly! besides, the markets really have all different types of things. for fancier clothes, there is one "shop" in stanley market that has children's 3 piece suits and fancy party dresses. they are so much cheaper than what you'd spend in a proper shop....
if you do try stanley again, do go during the week and around lunch time... all of the tour groups are busy at jumbo having lunch at that time!
