I think when women self identify as “bimbos” these days they’re usually referring to the purposeful reclamation of hyper feminine aesthetics, interests, and behaviors and not so much the original pejorative. It’s an aesthetic choice. The aesthetic is frequently referred to as “bimbocore” Examples would include lots of pink, heavy makeup, heels, false lashes, bleach blonde hair, etc. It’s sort of a subversion of patriarchal beauty standards since the intent is self expression and not conformity.
