LONDON–As a design school with countless success stories, Central Saint Martins sets instant expectations and usually more often than not manages to fulfill them.

This time, it was the second year BA jewelry design students’ turn to wow us. On April 1, the group put on an intimate show, an “exploration of what it means to be sustainable,” complete with organic wine and entirely-recycled paper goody bags. Indeed, this was the first time in their six-year-running annual show that sustainability was added as a key element. This was to demonstrate that ethical challenges can be turned into a positive catalyst. As-ever with Saint Martins you can expect a performance, and the opening pieces–structured bamboo bodily extensions by Steph Bila and a dripping wax choker by Crystal Burden–gave way to complex metal and biodegradable costume wear in sculptural shapes and forms, showing a vulnerability and softness that often comes with ethical considerations.
