I realise that this message might be been tongue in cheek but really, is this the type of message we should be sending people?
Just because I am fat that doesn't mean I don't want to go shopping with my friends! What if my thin friends and I want to go shopping together, do I ask them to wait outside for me while I browse your rails and see if anything takes my fancy? What if I want their opinion... do I need to tap on the window and get them to sign language their opinion through the glass? Of course not!
I understand that it is not your job to make people feel comfortable or to put together a fashion range that it is inclusive, but you have put yourself up their as a plus size model and so that is what you should be doing. As some one who has worked hard to be in the position of influence you should be telling people that the size of their waist does not matter, that there are so many more important things to worry about than what you look like and that you ABSOLUTELY have the right to enter any shop you so want to, no matter your waist size!!
Please think about your actions and your words, we should be working to bring different body types together not tear them apart!
