Her hair is styled in a messy updo with long loose strands falling down one side. The messy hair set against the smooth shimmery fabric of her glamour gown is a dramatic contrast that offers sexy elegance.

Notice how her large necklace complements her formal hairstyle.

Her dress is lovely but the cowl falls a bit low and the "belt" around her waist is too wide, making her look bigger. (It is also too bit low for her figure.)

But it's a good length, falls nicely, and makes her shiny high heels stand out—unlike many gowns which hide them.

Updos with tendrils are popular prom hairstyles, but many of them aren't high enough. High prom updos with loose strands are sexier.
