Happy Lovin' Baseball Cap

Plain black baseball cap with a Velcro strap to adjust the size in back. Nothing too noticeable here except the bright pink smiley face with hearts for eyes right up in front on the cap. I'm a dude, but I was considering wearing it as kind of a punk-rock irony thing. I never got around to it though. Still, should I call it unisex in the listing? Can I do that? I'm not sue Poshmark has a unisex option.
