With the fall season officially wrapping up in December, we rewind and take a look back at the galas, benefits, and fund-raisers that stood out. From chair-raising chandeliers to hair-raising exhibits, here are the creative event ideas and designs that were inspired by a range of causes.

In October, the Adrienne Arsht Center for the Performing Arts of Miami-Dade County and Arsht Families hosted its childrenâs Imagination Ball. The afternoon event featured immersive activities and a light and dance show by iLuminate on the Lynn Wolfson Stage of the Ziff Ballet Opera House.

At Lonely Whaleâs Into the Blue Gala, which took place at the Prince George Ballroom in New York in October, straw-sucking guests got âattackedâ by a stray octopus-like tentacle in the #StopSucking photo booth by the Bosco, which debuted the technology at SXSW a couple years ago.

LâOrĂŠal Paris hosted its 13th-annual Women of Worth awards, a philanthropic program that honors women who are making a difference in their communities across the country, at the Pierre hotel in New York in December. Jes Gordon handled the eventâs design, framing out the entrance to the dining room with an archway of branches and using a palette of rich purple hues, along with sparkling table linens.

The 25th anniversary of the Knock Out Abuse Gala raised $1 million in November to benefit women and children who are survivors of domestic abuse. Notable speakers at the event, which was held at the Ritz-Carlton, Washington, D.C. ballroom and designed by Events by AndrĂŠ Wells, included former Virginia Governor Terry McAuliffe, Senator Mark Warner, and D.C. Mayor Muriel Bowser. The decor featured plenty of sparkly silver sequins and glitter, accented with red, to commemorate the silver anniversary.

In November, Tyger Productions transformed the Cyclorama at the Boston Center for the Arts into a sparkling purple space for the Boston Purple Party 2018, benefiting the Pancreatic Cancer Action Network. The gala's co-chair Ty Kuppig of Tyger Productions and his team suspended floor-to-ceiling panels of reflective paillettes to create a more intimate setting within the large venue.

For this yearâs event, Stoelt Productions ditched the traditional gala format, instead creating mini âstudiosâ based on those at the Inner-City Arts campus so attendees could experience what the organization offers its students. The event was held at City Market Social House in Los Angeles in October.

The New York Public Library hosted the 2018 Library Lions Gala in November, with honorees Ron Chernow, Francis Ford Coppola, Jessye Norman, Claudia Rankine, and Elizabeth Strout. The event raised more than $2.7 million. Once again, event designer David Beahm transformed the Rose Main Reading Room into the galaâs dining room with floral projections by L&M Sound and Light cast on the walls and table decor that included white blooms.

The dinner, which was held in November at New York Hilton Midtown, honored designer Diane von Furstenberg with the Freedom Award and Larry Fink, chairman and C.E.O. of BlackRock, with the John C. Whitehead Humanitarian Award. The annual dinner raised $16.8 million to support the organizationâs humanitarian work. The table centerpieces were mirrored cubes featuring photos of refugees.

In December, Catholic Charities hosted the 29th-annual Spirit of Saint Nicholas Ball at the Hilton Chicago. The event raised almost $1.5 million, with proceeds benefiting the child development centers, after-school programs, counseling services, and teen parenting centers the organization provides for children throughout the Chicago area. The tables featured Father Christmas figures as centerpieces.

At this yearâs event, held at the Four Seasons Centre for the Performing Arts in Toronto in November, guests enjoyed a dinner created by Nota Bene executive chef David Lee on the stage of R. Fraser Elliott Hall. A close-up shot of roses was projected on the large screen behind them.

Gabrielleâs Angel Foundation for Cancer Research hosted its Angel Ball, which raises money for blood cancer research, in October at Cipriani Wall Street in New York. Artist Fer De Silva was on hand live-painting his iconic hearts; he also created an interactive installation.

In November, the Ontario Science Centre in Toronto hosted its annual RBC Innovatorsâ Ball, raising more than $730,000 to support the centerâs community access programs.

Cooper Hewitt, Smithsonian Design Museum honored the 2018 National Design Award winners with a cocktail reception and award ceremony at the museumâs Arthur Ross Terrace and Garden in New York in October.

To celebrate Rethink Breast Cancerâs 17th-annual Boobyball fund-raiser, which was held at Rebel in Toronto in October, guests dressed in denim and cowboy boots for the âWild Westâ theme. Partygoers even rode a mechanical bull.
