This petition is probably very old, and unfortunately, even if it had 1000s of signatures, won't change a thing in the modeling/fashion industry. The petition was put up by Canadians who felt that the 5'7" minimum requirement for Canada's Next Top Model was discriminating against short, beautiful women. I do agree, and did sign it, but knowing the fashion industry (and the media pretty much brushing off short women doesn't help...every time I hear about size issues, it seems to be plus, plus, plus...)
Other petite petitions include:
A More Petite Friendly Fashion Industry (which I created over a year ago)
A Petite Board for the Lou Lou Magazine website (Lou Lou is a Canadian shopping mag...kind of like Lucky)
