Of course, if you're a women's clothing store you might wind up iterating yourself into a men's clothing store if you follow that advice too strictly. :)
Which is only a problem if you want to have a women's clothing store in preference to making a profit.
There was a TV program about a shoe manufacturer in the UK a few years back that started making larger womens boots. They realised later the demand was driven by transvestite males and that they could make more money in that market and so transitioned from being a womens shoe maker to catering for leather-fetishists and transvestite males. They simply followed the profit.
Inline with your comment, not all companies would be happy to make such a profit-driven move; but I suspect few shareholders would care not to.
