I also brought 2 (one suggested for medical used and the other with 6 wire to support) but used only once/twice! Because it makes me feel so uncomfortable and hot (feeling itchy too) around my waist (it was Jan/Feb04)!! So wasted afterward!!
Suddenly remember there's a shop in TaiKoo Shing that may be less expensive, I mean when compared with Nini, 0101 or Gennie. It is located at the shopping mall of 康山花園... accross the road of McDonald's ... I think it's called "Chez Michelle" or something like that...
I bought quite a lot of maternity clothing before my first son was born.. from 0101 and Gennie...quite expensive but some of them were not even worn once and then my son suddenly came out :-( I gave it to my brother-in-law's wife and then when I got pregnant again (accident ah ) I got some of the clothings back and only bought several for work from Nini in New Jade Garden ...one set of shirt and pants cost me $4xx plus... My friends had given me some during my first pregnancy and my sister also helped me to buy from a shop in Ma On Shan which is not expensive ah... you may ask your friends to help you buy if they know of any
