I have absolutely no idea if my bridesmaids shaved their armpits, and nor do I care.
I absolutely agree with everyone who is saying that suggesting this girl shaves, or even buying stuff and leaving it around and making 'helpful but not coercive, oh, no' suggestions is actually telling your kid in no uncertain terms that their body does not meet the required societal standards. Even if you do tack on the 'only if you want to' crap.
Yes, I do have a 14yo girl. Fortunately she makes her own mind up. She dances competitively and spends about 10 hours a week with her arms stuck up in the air and her legs on show. She doesn't shave at all for most of the year, but does whip the hair off during the month long competitive season, purely because she is aware that most people have an aesthetic sensibility where dancers are concerned, and yes, she DOES display her pits to everyone. For the rest of the time (which includes the summer, as comps are on when the snow is on the ground) she is hairy. Even in strappy dresses. No one gives a shiny shit, least of all her. In other news, she also doesn't bother wearing make-up unless she's on the stage. Performing has given her a strong sense of 'things we do because they are expected' and a freedom to go against the grain when she doesn't want to 'perform' femininity as required by social convention. Even in a strappy sundress.
I'd like to say this thread is unbelievable, but sadly, it's no surprise that the world is stuffed full of women who want to indoctrinate their daughters that they aren't good enough, aesthetically speaking. The veet dudes are counting their millions and supporting you all the way, ladies.
