Hi,
Sorry if this seems a silly question but..... are there many places around the Christchurch area to buy size 18/20 clothes?
We're moving over in Sept and here in the UK I live in Evans, BHS etc....what is there in NZ? I'm seriously wondering wether to 'stock up' on clothes here to bring over! I wouldn't be so paranoid if I was a 'normal' size but I'm 18/20 and also petite! (It's really hard getting nice stuff here and I have no idea about your shops! HELP!!!! :? :mrgreen:

Thank you!
