Olivia Culpo's Oscars gown is made from glass

Olivia Culpo’s Oscars dress was not only breathtakingly gorgeous but it also had a pretty strong message behind it.

The 24-year-old model-and-actress stunned in a custom creation by Marches, with one-of-a-kind glass beads made from chalices.

The gown is aimed at raising awareness for Stella Artois and Water.org to bring clean water to developing countries for their “Buy A Lady A Drink” campaign.

The designers used elements from the drink's company's limited edition chalice in their ideas for Olivia's gown, with the shimmer, gold accents and silhouette proving a source of inspiration, and their finished creation will incorporate stunning glass beads.

"We wanted to use the red carpet as a platform to get this important message across,” designer Keren Craig told Yahoo Style.

"So when we started designing we asked ourselves, 'how can we make a dress for Olivia that's beautiful, Oscar-worthy, and yet still really shines a light on this cause?'"

They then spent three months talking to the former Miss Universe about their idea, and came up with three possible designs and Olivia was delighted to be involved in the campaign for Wter.Org, which was co-founded by Matt Damon and Gary White.

"I always like to try something new on the red carpet and this is such meaningful way to do it. The fact that it's going to help provide water for people across the world is incredible,” she told Celebuzz.

For every limited-edition chalice sold, Stella Artois will assist Water.org in providing five years of clean water for one person in the developing world.
