Several people seemed to be bothered by the question in the title and I do see some validity to the concerns. A better question would be...
"What if your preferred wardrobe were suddenly normalized to the point that most of the items you now buy in the women's section were available (and widely purchased by "normal" men) in the men's department?"
In that scenario it would no longer be crossdressing which I think was the issue most seemed to have with the initial post.
My answer would be that I'd still go to the woman's section to look for things that stood out from what most see as 'manly'. I'd like to see it normalized to the point where I felt comfortable and acceptable going out to the mailbox in a nice sundress, but not necessarily to the point where every man in the neighborhood was going out to the mailbox in a nice sundress. I like feeling unique. But, I dislike having my uniqueness turned into a joke or worse.
