look up any word, like lemonparty:
 
1.
The certain glow a girl has on her prom night with a twinkle in her eye and a perma-smile draped across her face. She is all dolled up and looks her best in her new dress. Her hair and makeup have taken hours but its worth it because they look perfect! She holds her head up high and walks proud because she knows she looks "prom pretty".
The girls that participated in the Win the Ultimate Prom contest looked extra prom pretty because they had an extra $25K throw the Ultimate Prom!!!

The type of pretty girls get for prom nights only. It involves pink shades of makeup, a very poofy dress, and her hair usually is in a complete updo (everything tied up with a poof of curls at the top of the head) with two skinny tendrils on either side of the face.
Mary's wedding was gorgeous, but she looked a little too 'prom pretty' for her own wedding.

Prom Pretty defines a woman as feeling confidant about herself and one who takes extra effort to look and feel good about herself in every way. All women have Prom Pretty within them.
