You should wear what you feel confident in wearing. You should go with a look that suits your age but, is classy yet sexy and confident. Try a more elegant look without dressing it up to much. Maybe wear a longer dress with a slit up the side and dress it up with some nice earrings and a necklace to show off your neckline. Don't let yourself hang out but, just enough to see a dangling piece of jewelry. maybe pull your hair up and reveal your neck with a classy ponytail or loose bun.
