Could it possibly be related to women's relationship to clothes? I was wandering around the centre of the major UK city that I live in, the other day, and it suddenly struck me how many thousands of square feet of retail floorspace are devoted to the sale of women's clothes and how little (relatively speaking) to men's.

Most women seem to adore clothes (I'm not knocking this , you understand - just an observation) and are expected to experiment whereas men tend to be much less interested and, like me, may actively hate clothes shopping. Thus the number of men who go as far as dressing in women's clothes tends to be in a minority (and if you produce some spurious statistic which 'proves' that 40%, or whatever, of men in the UK/US are secret cross-dressers I won't believe you!).

Also, of course, as has been pointed out above, many women can look sexy and attractive in anything whereas men in women's clothing often look grotesque. Actually, I saw a man in drag last Saturday and although I completely support his right to wear whatever he likes, I'm afraid to say he looked grotesque!!
