Three Bimbo Types: The Clown, The Innocent, and The Debutante.
Bimbo can most easily be divided into three distinct archetypes. The Clown, The Innocent, and The Debutante. These archetypes are not absolute, they come in many variations and their traits can and will overlap.
The Clown, also known as The Free Spirit or The Wildcard, usually shows up as the comedic relief. They can be loud, showy, excessive, and obnoxious. Their sexuality is very self-assured, self-aware, and playful. The Clown's main concern (if any) is having or spreading fun, "fun" in this context being completely up to their individual style and personality. To give a very stereotypical example, a goth clown may have the most fun watching very violent horror movies or playing with spiders. Another clown could have the most fun (Incidentally) causing a ruckus or being mischievous, it's all about perspective, the possibilities are pretty much endless.
Examples of this archetype include but are not limited to: Jeannie (IDOJ), Pinkie Pie (MLP:FIM), Harley Quinn (BTAS), Synclaire James (Living Single), Jayne Mansfield (films and public persona), Elvira, Mistress of the Dark
The Innocent, also known as The Ingenue, is just as the name suggests. Not only helpless but often unaware and wholly out of her depth. Her inexperience and or meekness makes her prone to being taken advantage of. Despite this, she (usually) remains positive, kind, and happy to help. Unlike The Clown, The Innocent's sexuality is typically portrayed as natural, uncomplicated, and unintended.
Examples of this archetype include but are not limited to: Marilyn Monroe (films and public persona), Weena (The Time Machine), Lorelei Lee (in the novel), Elissa Megan Powers (Empowered)
The Debutante, who could also be called The Alpha Bitch, is probably the most popular in the modern era and who you're most likely to come across in real life or on social media. Her sexuality is mainly a means of control. She puts a lot of time, work, and effort into her appearance because beauty is both her business and capital. While she may, at times, enjoy and indulge in carnal pleasure it's far from her main concern. Being the most or unattainably desirable is how she knows she's better than others, how she's able to acquire and maintain control. The Debutante values social standing above all else, to her it's a matter of life or death, she would die without overwhelmingly positive attention.
Examples of this archetype include but are not limited to: Regina George (Mean Girls), Heather Chandler (Heathers), Courtney Shayne (Jawbreaker), Heather (Total Drama Island), Cleopatra Smith (Clone High), Jeannie II (IDOJ), Emma Frost (X-Men), Panty Anarchy (PSG), Ginger (Gilligan's Island), Holly Golightly (Breakfast at Tiffany's), Kim Kardashian, Rarity (MLP:FIM)
These archetypes are combined, remixed, and subverted so often it's hard to find pure examples (I tried my best, and even then this is just reducing them to their base archetypes and do not accurately describe every single one of these characters), but this is a good thing.
It leads to nuance and diversity, and many of the most popular bimbo characters are mixed or subversions. Chrissy Snow (Three's Company) is a Clown and an Innocent. Elle Woods (Legally Blonde) arguably includes elements of all three. Romy and Michele's High School Reunion follows two clownish Innocents who realize they were bullied by debutantes. As far as I know, all bimbos exist somewhere along these lines (or perhaps on an axis) but we shouldn't view this as limiting, when you think about it the combinations are really seemingly endless, and I didn't even cover sub-archetypes! Many Debutantes are mean but they don't have to be. Innocents don't have to be completely pliable, you can do (or be) whatever you like, even moving from one archetype to another."
