I bought 1pack of training pants (5pcs), 1 set (2條) shorts (針織料, but 牛仔布look), & 1 set Tshirt (3件) & incld. postage is <$300. average $ is around $100/item (some come in a set of two / or a set of 3).
I bought size 95 for my B (25lb) so he can still wear them next year because the japanese size is more slim than the 鬼佬size.
