it's easier to fret and fume about a few polo-necks and skirts in just one shop
Again, spectacularly missing the point. Sorry to have to shout, but IT IS NOT ABOUT THE BLOODY CLOTHES. Turtle necks and full length skirts were not invented last week to appeal purely to women who are, or choose to be restricted by their religion or their culture.
I've just looked at the M&S website and every category of clothing is factually described with the one exception of Modest Outfits. Nothing else is described by value judgement or by perception in the eye of the beholder. So let's turn this on its head and imagine all the clothes with the exception of 'modest' clothes are described by the message they send out, or how the woman who buys them wants to look and feel.
To those who seek out 'modest' fashion, how would you feel about this?
You go into M&S or onto their website and the clothes are divided into two types - those that might fulfil your brief of 'modest' and then everything else.
Now imagine the 'modest' stuff has no further description attached to it but everything is grouped together under various banners using defining words such as :
Alluring
Feminine and Beautiful
Stylish and Elegant
Cutting Edge, Fashion Forward
Dynamic and Professional for Strong Successful Women
Progressive and Modern
Youthful and Fun
And the clothes available to you, taking into consideration your religious and cultural restrictions, are not categorised as any of those things by M&S.
How would that make you feel?
