Well, while most models seen in media are completely stick thin, it is a refreshing change to see women like Beth Ditto in fashion photo shoots.
However, agreeing with what has already been said, this can also send out the wrong message to impressionable teenagers.
Really the only thing that could be done would be to put healthy weight range people on the cover of magazines or in fashion shoots to try and please everyone but I feel as if we will be waiting a very long time before that ever happens.
Although this has been taken up by the media quite recently and a lot of people have expressed outrage at the lengths editors go to distort a photograph.
In Scotland as well they are planning to try and ban photoshop or at least get the magazine to place the words "This has been altered" on the image.
