One person’s used uniform is another person’s fashion find. Or so was the thinking of Heron Preston, a founding member of the art/disc jockey/design collective Been Trill and designer, who presented a collection in collaboration with the Department of Sanitation New York on Wednesday evening. (The venue was in and around the Spring Street Salt Shed, an award-winning structure that houses 5,000 tons of salt for city winters.)

“I just noticed service workers weren’t as celebrated as the F.D.N.Y. or the N.Y.P.D.,” said Mr. Heron, who has also worked with Nike as an envoy to the fashion and nightlife world. “Without them, we wouldn’t be able to live in this amazing city. So it’s about shining a light on them and celebrating the work that they do.”
