When should I start preparing for prom?

As a high school student eagerly anticipating the upcoming prom season, I find myself wondering when is the best time to begin preparing for this special event. Should I start planning my outfit and securing transportation months in advance, or is it sufficient to do so a few weeks before the big night? Additionally, how should I approach selecting a date, if I haven't already, and what steps should I take to ensure that I make the most of this memorable occasion? Balancing academics, extracurricular activities, and personal life can be challenging, so I'm seeking guidance on how to effectively manage my time and prioritize my prom preparations.
