Question

Four students at the University of Hefei, in eastern China, recently proved that you don’t have to spend a small fortune on a designer dress to look attractive. You can make it yourself, for free, using only plant leaves. Photos of the leaf dress have been posted on social media for about a week, and people still can't stop gushing (交口称赞) over them.

The team behind the unique dress ---two girls and two boys--- got the idea for it over six months ago, while trying to come up with an interesting project for the annual “Animal and Plant Specimen Contest” at the University of Hefei. During that time, the girls couldn't stop talking about how beautiful the dress worn by actress Zhang ziyi at the Cannes Festival looked, and one of them suggested they try to recreate it out of plant leaves.

They asked for their teacher’s advice, and even though he considered it difficult to succeed, they went with it anyway. After researching the best way to use plant leaves as fabric (衣料), and coming up with a design for their dress, they started collecting the leaves. Some species were readily available on campus, but others were not. So they had to travel to Tianzhu Mountain to collect them.

To ensure that the collected leaves didn’t shrivel orrot (枯萎或腐烂), they removed the flesh by boiling them in alkali and sodium carbonate solution (碱和碳酸钠溶液) for about two hours. They struggled to get the proportions of alkali and sodium carbonate and the boiling time just right, to ensure that the flesh could be easily removed without damaging the skeleton of the leaf. Through trial and error, and with their teacher’s guidance they were able to come up with a perfect formula (配方).

They could only work on their special dress after class and on weekends, so it took them nearly four months to complete. That’s a pretty long time, but it all paid off when one of the girls got to finally put on the leaf dress and show it off to everyone.
