Her Queen of Limbo costume she got in the New Mutants arc year before last. Not a bad costume, but it sure ain’t the classic.
When the Bowen was released Marvel had rules about women’s costumes. Women were covered up in the comics and merchandise.
If modern comics are any indicator, those rules are long gone. Up until she became queen at the end of New Mutants, she was back to wearing her classic costume.
Personally I’d prefer a Madelyn PF in the classic costume. I’d be less likely to buy otherwise.
