Olivia Culpo arrived at the Dolby Theatre for the 89th Academy Awards looking breathtaking in her Marchesa gown on Sunday, Feb. 26.

Dripping in frilly beads, the 24-year-old had her hair pulled back for the red carpet moment.

Glamour aside, the 2012 Miss USA brought attention to the importance of clean water by wearing the grey-blue dress made from Stella Artois Chalices.

Yep, that's melted beer glass in Marchesa form in those intricate beads.

The collaboration with the beer company and Water.org promotes the "Buy a Lady a Drink" campaign.

As Culpo was getting ready for Sunday's event, she encouraged her social media followers to spread the word on the global water crisis.

Co-founded by Oscar winner Matt Damon, Water.org emphasizes clean water for developing countries.

“[The dress is] in partnership with Stella Artois and Water.org. Stella Artois created chalices and for one chalice sold, five years of clean drinking water is provided for someone in the developing world,” Culpo reiterated on the red carpet. “So this dress is actually made out of the chalice pieces, and it’s encouraging people to get involved in the water crisis and buy the chalice.”

In terms of the dress's design, Culpo revealed, “It’s sort of cascading. The crystal represents the water, as well. We knew we wanted tears.”

Culpo praised her team as well for incorporating charity and fashion for the winning look.
