We can avail ourselves of so many more options in casualwear.  We can obtain the pieces more inexpensively (everything shown here cost less than $30).  And we can throw them together somewhat indiscriminately.  I called this the Christmas Outfit after I put it on because the pants (Banana Republic outlet) are sort of green and the sweater (...Banana Republic outlet) is reddish-orange.
The other blogs for folks who wear traditionally male clothing are obsessed quality over quantity.  In practice, this means one Japanese-knit $200 cashmere sweater, manufactured by a company whose marketing department managed to get the bloggers' attention, instead of six outlet cotton sweaters.  Sure, there are ethical issues to consider before buying inexpensive clothing--living wage and safe conditions for the workers overseas, for example.  If you have $200 to spend on a sweater, excellent.  For some of us, that means buying one sweater per year.  For those of us with style blogs, that seems...restrictive.
Anyway, socioeconomic concerns are a topic for another post once I've had some time to woolgather on the topic.  Meanwhile, picture this outfit on a feminine-presenting person whom you find attractive, and tell me that it wouldn't work just as well for them.
