March shouldn't be that cold. I've just finished my 1st BB clothes shopping (mostly the undershirt a.k.a. monk's gown) and couple those toad outfit that you put on top of the undershirt.
Surprisinly, I've got all that at a reasonable price at Wah fung Chinese dept store at North Point. The qualit is the same at $33 (I've compared that with what I saw from Sogo at $119) just not made in Japan or the color/pattern is not as new as JPN one. They are all 100% cotton. I don't care as the baby out grow it so fast and he/she can't tell the difference anyway.
