now SOGO 21/F has sale, some nursing bra & 大肚褲仔 also $100/3 pcs, I bought them on May, it is OK. This promotion started 7/11 - 7/15, you can go to take a look.
I also bought 3 cotton/non-wired nursing bras from Mother World for home/sleeping use. When go out I will still use wired nursing bra with some paddings coz I think the shape looks better.
We may add the breast pads during nursing period. They always have buy-2-get-1-free promotion.
