At her kitchen stove, fashion designer Caroline Zimbalist looks like an alchemist at work as she stirs a pot full of corn starch and a thickener made from seaweed. The peppermint-scented mixture glitters as she carefully pours it into silicone molds of hearts and leaves.
When the material hardens, Zimbalist will stitch it into unique, made-to-order dresses that she sells on her website. She hopes her designs, which have been worn by celebrities including Chappell Roan, will put a spotlight on materials that aren’t sourced from planet-polluting fossil fuels, such as oil.
