Here is a Batgirl BoM skin (but can easily modified to make other Bat costumes):
Batmask only (copy and paste over a head texture and upload:to make a mesh head or BoM skin):
Batgirl skin upper:
Batgirl skin lower:
Apologies for no images as image preview isn't working at the moment but can be viewed at the link location. Just add some dark shoes or dark toned boots, shoulder length redhead hair and a black cape to complete the Bat outfit, no UUID as this is from OpenSim but can be uploaded to make a BoM skin as textures. Some Batgirl outfits are navy or dark blue toned but it's up to you if you want to mod the textures to those tones. This is more of a cosplay type of Batgirl outfit instead of precisely matching a mainstream Batgirl appearance.
