Some theme ideas for a 21st birthday party include Black and White, Tuxedoes and Tiaras, School Days and a "When I Grow Up I Want to Be…" party. A 21st birthday is typically a time to let loose, and these fun themes ensure that both attendees and the guest of honor all have a great time.

A Black and White party makes for a truly stylish 21st birthday celebration. Guests can wear cocktail dresses and tuxedos, and the party can also be decorated in black and white. Similarly, a Tuxedos and Tiaras party is a great theme for a classy 21st birthday party, especially for a birthday girl. Female guests can dress up in high heels and luxurious princess dresses, while males should probably stick to formal wear. Crystal cake toppers and other decadent decorations can help guests feel like true royalty.

A School Days theme gives attendees an opportunity to relive their younger years and the guest of honor an opportunity to bid goodbye to youth. Decorate the room with blackboards, homework or anything else that's reminiscent of childhood. Guests can also dress up as their favorite school stereotypes, from jocks and cheerleaders to nerds and Goths. Similarly, a "When I Grow Up I Want to Be…" party lets guests relive their childhood fantasies. Have each guest dress up as their dream career from their younger years, whether it's an astronaut, a veterinarian or a movie star.
