The first one is a red velvet halter jumpsuit, with feather trim, tails and headband. The second one is red too, oops… was red ! My guess it someone washed this devil costume with angel costume. The white color run from the angel costume into the devil costume you see now. Good explanation (But where is the pink angel costume…)
And so it’s pink, and it exists for child too. And I find it cool actually !
