Whilst sustainability and eco-friendly options are becoming more and more popular among the general population, it's hard to believe that the countless outfits for each awards season could be helping increase awareness of the part fashion plays in environmental concerns.
That being said, a number of celebrities and stylists are putting their all into ensuring that their red carpet dresses and outfits are in line with their sustainable beliefs.
The rise in popularity of vintage dresses, and the use of cruelty-free and eco-friendly materials has meant an increasing number of stars have been choosing sustainably when looking to use their presence in the public eye for good.
From utilising upcycled household items like plastic and glass bottles to keeping sustainability at the forefront throughout the manufacturing process, these are the celebrities paving the way for sustainable dressing on the red carpet.
Take a look at the most daring, dramatic and environmentally-sound pieces to have appeared on the red carpet in recent memory.
