Maternity shops in HK are far and few between and good ones are even more rare, and then when you do find them you might find yourself paying as much as double the price of stores in Europe, Australia or the US. So if you can shop when you travel do so. Otherwise try these ones.
Unit 501, Pacifi House, 20 Queen Road Central
They have a really wide range of maternity clothes (specially jeans and trousers) but they are expensive and some of the same brands are carried at Bumps to Babes for less.
Bumps to Babes
5/F Pedder Building, 12 Pedder Street Central (larger branch in Horizon Plaza, Ap Lei Chau)
Apart from maternity wear this is your one stop shop to everything you would need for a newborn.
8 On Lan Street Central (also branches in Causeway Bay and TST)
Some good work clothes here
7/F, 68-70 Wellington Street Central
Fairly new in HK, can be expensive but useful for a special occasion dress as well as some very pretty night gowns with inbuilt nursing bra.
Queens Road Central
They have a good range of casual clothes and great value for money (some great
weekend cargos !).
Very limited maternity section in HK, but what they have is very cute.
