I personally really enjoy a good genderbend. I think that, if done correctly, it can be really creative and a good solution for someone who doesn't want to/can't crossplay. I do get what you mean about some people using it as an excuse to "sexify" an outfit though. However, if that's what they choose to do, then it's their choice I suppose, and more power to them for being comfortable enough in such outfits.
