On the one hand, a late night comedian said something to this effect regarding the arrival of Manties a few year ago: "That's okay. I'll just stick to panties." Similarly, Mantyhose may seem a bit too exotic to some guys that still are willing to take a chance on pantyhose. Don't expect it to cut into the market so much, especially if the style is compromised.
However, this guy (correct gender) is just spewing close-minded cynical anecdotes loaded with homophobia and gender essentialism. He's less funny than me, and I don't even get paid for my material.
