Emma Watson's Met Gala Dress Made From Recycled Plastic Bottles

Los Angeles: Harry Potter star Emma Watson's Met Galaoutfit was made from recycled plastic bottles.With the help from Eco Age, Calvin Klein Collection created an off-the-shoulder bustier, wide-leg tailored pants and a long detachable train for the 26-year-old actress.

And unlike the other gowns that will never be worn again, separate pieces from Emma's outfit can be used again.

Emma's stylist Sarah Slutsky explained everything in an Instagram post:

Tonight, the stunning @EmmaWatson on the #RedCarpet at the Met Ball in a look crafted by the incredible team at @Calvinklein. With the help of @ecoage this 5 piece look is created from 3 fabrics woven from yarns all made from recycled plastic bottles. Plastic is one of the biggest pollutants - being able to turn this waste into a high quality material is a real success story. Also this beautiful look was designed with the intention to be repurposed for future use; the pants can be worn on their own, the train can be used for another red carpet - the ultimate #30Wears! #MetGala2016 Makeup: @therealdotti Hair: @visapyyapy
