Pretty sure Clawdeen is Boo York, but her clothes aren't original to her - her shoes are Dance Class Operetta's, and I'm not 100% sure but I THINK her dress is 13 Wishes Abbey's? It's difficult to tell from the photo. It would make sense if the Abbey is the 13W version though.
Gigi is NS, yeah, but her dress is Elle Eedee's, while her boots are Signature Clawdeen's. Not sure about her earrings, sorry.
Agree w/ 13 Wishes for Abbey (I'm not 100% sure since I get mixed up with her dolls). Her dress is Dot Dead Gorgeous Spectra's, not sure whose boots she's wearing.
