The type of costume could be a factor really, is it a Classic or Modern Haley costume. The classic is a full fledged catsuit deal, not the type your likely to find in a normal costume store, her modern outfits tend to not so much be a costume as slutty outfits with bi-colored wigs.
Just look at her in Batman the Animated series where she originates and say the Suicide Squad film and the extreme difference becomes clear as day.
