Hi Louis. :)
Probably a huge mix of reasons. A whole lot of misogyny - especially the kind instilled into young girls against other girls. Also, I always found them hard to relate to. A group of 5 women that are 90 lbs soaking wet and 5′4 wearing $500 jeans with weaves of perfectly curled but also straight and silky hair down to their waist …are not me, nor are they really any young/teenage girl. If somebody really wants to try to do a girl band, find one with some NORMAL relatable girls. Think Spice Girls, but BETTER. And no stupid stuntin like Modest does.
There needs to be black girls and brown girls (without white washing them) and white girls, all of varying heights and weights and different builds/body types, with different hair and different overall styles. Some straight, some queer, a trans girl! PUT IN A FAT GIRL. A girl with HELLA FRECKLES or a port wine birthmark. Something that makes them unique. Think about girls who NEED an idol, girls who NEED representation. Girls can identify with people that look like or have something else in common with them. Girls need to see girls with thighs that touch in affordable Forever 21 clothes and accessories that a girl can actually buy with her babysitting money.
They all need to be DIFFERENT from one another, but they need to all have at least something that every girl can identify with, and they need to all be focused on a similar goal/theme (Think Girl Power!) Pick outspoken feminists who don’t live for men’s pleasure, who don’t only sing about boys. Pick a group of girls that can sway young girls away from the internalized misogyny that makes them hate other girls in the first place, and watch them flock.
Send me a message off anon for the address to send my royalties check, I’m also willing to manage. I have great ideas for boybands too. <3
