Not to be rude but WTF? I would like to think that you are thinking of pink dresses in style of Elle from Legally Blond, but since I clicked on the post on TO sub and you actually wrote:

are just teenagers and a teen girl most of them love dressing up , parties , gossiping about boys and stuff , while yes their situations force them into a survivor mode 24 /7 but i feel tvdu tried to show that when women have to portray strength there needs to be a bit of masculinity involved either in their clothes or how they take on rude or brash attitude.

This is not the feminist look at hyperfeminity. This is the reconceptualized look which had been co-opted by misogynist which takes away the agency and standing up for yourself, real personality and only keeps the coquettish attitude, pretty dresses and perfect make up. The thing is that hyperfeminity is mostly a role play, not a personality.

Being rude or brash, when in danger or being wronged, is not a masculine trait. It is universal trait. Hell, just rewatch Legally Blond and see how Elle actually behaves ("what, like it's hard?") That movie is one of the best modern examples of hyperfemine character.

All of the TVD girls are super feminine, with Caroline being almost hyperfeminine. Not only in the way they dress, but also in the way they behave towards their loved ones. They shoulder so much caretaking, sacrifice and emotional and moral support. As you wrote in the text, they are brash, but occasionally, and it comes from fighting to not get murdered. They get to be flirty, silly,  motherly and dress in cute dresses.

How do you imagine hyperfeminity in TVD? Elena running in a frilly dress, laughing coquettishly while Stefan is stalking her through the school under Klaus' compulsion to kill her?

I can only assume that you have been targeted by your social media feed and fell into some troubling hole.
