Asda have a policy of not including size zero (UK size 4) models in their adverts. However, in a show of utter hypocrisy, Asda will now stock size zero clothes in their George range of clothing. Read about it HERE.
It seems that ethics have no role to play in Asda or Walmart and that encourging or taking advantages of people with eating disorders is more important that having real values.
I'll be avoiding Asda. I'm sure they'll not miss my trade, but if others did the same ?
