So, this backdrop appears to cover up the parts of my HA's hair that goes beyond the head outline. (Hover to see what I mean) First off, is this just my computer/browser, and second, will it actually overlap everything outside of the HA's outline if I buy it and put it on?

Backdrops always show up like this in previews. If you put it in your wardrobe and put it on you can manipulate the position of the layer it's on to move it over or under stuff. That's how some zombies hide their zombieness, actually c:

Go to your wardrobe and select it from the All Clothing On Subeta section. You can then put it on the very bottom layer and see what it looks like.

PS: I posted at the same time as Sapphira. :)

Thank you both! Haha I didn't want to buy an expensive backdrop and then look like a bald person with hair painted on. XD
