Being on the planning committee in a sorority can be an incredibly exciting and rewarding position! Not only are you often in charge of making decisions regarding recruitment and fundraising, but you also get to plan fun social activities for your fellow sorority sisters like choosing the party theme for the fall formal!

The good news is that there are endless formal themes for a sorority event to choose from and activities to host at each. To help you decide, we've narrowed down a few of our personal favorites, ranging from a classic casino night to a theme that's 'out of this world.'

10 Themes for Sorority Formals

1. A Night at the Masquerade

Everyone loves a masquerade and encouraging your sisters to lean into the theme and sport over-the-top masks will make for a night that no one will soon forget.

You can even expand this theme into a craft night social where people can meet up and decorate masks together before the ball!

2. Under the Sea

This classic formal theme is always a crowd-pleaser thanks to its colorful luminescent and eye-catching decor. One of the ideas we love to see when hosting an underwater bash is encouraging the guests to dress as mermaids or sailors!

3. CLUE: Murder Mystery Night

This formal theme will involve a bit more pre-planning, but with the right amount of people and active involvement, will be loads of fun!

Start by ordering a murder mystery kit online and choose from a wide variety of themes. Then assign out characters in advance and have everyone dress the part! When the night of the formal arrives, it will turn into hilarious mayhem as the murder mystery unfolds and the case is solved!

4. Old-School Hollywood Glitz & Glamor

Old-school Hollywood glitz and glamor is perfect for upscale formals, as it will allow attendees the chance to arrive in style and show off their best looks! Some prefer to lean towards a Great Gatsby night and make it wilder in terms of entertainment, even hiring out a live band.

5. Snowy Ski Lodge

Decorate the venue like a cozy ski lodge, or better yet -- throw the formal at a ski lodge if you live nearby! Dive into this cozy theme with a spiked cocoa bar or boozy drinks like eggnog and spiced cider for everyone 21+! If thrown in the fall or winter, this sorority formal will put everyone in the holiday spirit.

6. Enchanted Forest

Find a venue with an outdoor area and host an enchanted forest garden party! String fairy lights, mix colorful floral cocktails, and host garden games like croquet!

7. Let’s Set Sail

Underrated among sorority event themes is a cruise themed formal! Instead of dressing to the nines, have everyone arrive in their tackiest cruise wear and compete in cruise competitions themed to each 'port' for a grand prize.

8. Casino Night

Grab a drink, roll the dice and get ready to rake in some chips with a lively casino night formal! This sorority party is classic and will no doubt leave everyone entertained. Rent out different game tables and hire dealers so you can just focus on having a blast with your friends!

9. Adventure in Wonderland

An adventure in a wonderland cocktail party can make for a great formal! Dress in your wackiest wonderland attire, sample glittery themed drinks and hit the dance floor. When planning decor, you can rent colorful lights and a fog machine to make the space feel as mischievous and quirky as wonderland!

Creative and playful themes like this are also a popular choice for prom theme ideas for any groups looking to do something a little different.

10. Spacing Out

Send your guests out of this world with a space themed social event! Set the dress code to extra-terrestrial and hire a DJ to spin electric house jams until the early morning.
