Yes. If you wore than everybody would be calling you a slut. Plus only a perfect model type could actually pull off that dress.
I agree with the first person who answered. Modest honestly creates a sort of more mysterious and confident persona, assuming you do modest correctly. Plus, if you ever want to have a boyfriend who respects you, you have to respect yourself.
Personally. I wouldn't let my daughter wear through as An 8th grader. It might be a dress you wear later in hs. If it was a touch longer I would Say go for it. But modest is sexy too. Never forget that as a young woman!!
