New Brevoort Formspring

odd question but on kirby's cover to avengers #151 (the classic one with the big three announcing a new line-up), who is the woman on the left... i'd assume it was wasp with her placement right next to yellowjacket but the hair doesn't quite match whereas it looks a bit more like patsy walker's hair...but why would she NOT be in her hellcat costume... if you could settle this age old conundrum for me, it'd be welcome!
