Angelic Dreamz has a line of horror fashions and accessories for 16" fashion dolls coming out. And they are pretty darn edgy. These are made specifically for their JamieShow line of extremely high-quality resin couture fashion dolls...but these fashions and masks should work for most 16" vinyl and resin female dolls and 17" male dolls made by Tonner and the like. The shoes may or may not work though...and I am damn tempted to get those cheetah boots to make, well, a Cheetah doll (a Wonder Woman's villainess). Getting the whole shebang is UBER-pricey..the bulk of the expense coming from the weapons...so I recommend getting the masks because they are really spectacular...and those cheetah boots for me.
If you want them, you need to pre-order them ASAP in order to get them by Halloween.
