Too Much For A 13 Year Old?

Hi. I am thinking to wear a light pink/peach fitted blazer with ruched sleeve and a flower corsage pinned on, the top underneath is a a plain white tee and on top of that a plain creamy white crop top, paired with black skinnys and really low wedged brown gladiators , also just some accesories like a necklace and pearly bracelets. I want to wear this to a theme park that me and my friends are going to, but do you think i'd look fake an grown up?
