Poison Temptress

After the debacle that was the faux-Poison Ivy outfit that made this year’s Worst Haloween Costumes list, I knew I was destined the remind people that decent Poison Ivy costumes exist. Actually, you don’t really need to clarify Poison Ivy as “sexy” at all; she’s been depicted in countless provocative outfits in every medium Batman’s been in. It’s hard to get it wrong, frankly. This outfit isn’t stellar—it’s definitely a Poison Ivy Bikini, but it’s certainly authentic to the character. (Leg Avenue, $81)
