I know covers your base, but are there items that make it just slightly translucent or faded?

and have a few variants, but I think and * [item=Genetech SecondSkin V.2] and [item=Ghouls Choice Liquid Latex (Dark)] * are more what you're looking for? *Has color/pattern variants.

Hope that helps. :D

Thank you! This is extraordinarily thorough. All I'm really looking for, though, is something that will bring me down to 50% opacity, basically. Like a translucent vanishing cream

Unfortunately I think these are as close as you're going to get, and they kind of function just like the filters that listed since they all add a background as well. There are full versions of each meant to be used together to make your HA look like a ghost, in case that helps: [edit] There's also these white filters, which I think is what you're looking for but unfortunately the only really decent white filters are CWs: *I think this last one is hard to find

Yeah, if you like the backdrops then Darkrai's suggestions are where it's at. Otherwise, in terms of non-CWs, I think the really is your best bet, sadly. Maybe in a pinch.
