Hussein Chayalan's Airmail Dress with graphics by Michael Langkjaer and Rebecca Perry

Hussein Chayalan, made a papery material dress that could be folded into letter form and attached with stickers.

I love sending odd things through the post, a jar of jam and a par baked baguette probably the naughtiest. A painted t shirt with the recipients address painted on folded and posted and even a love letter on vegetables that I had in my shopping.
This wonderful dress by Hussein Chalayan really caught my eye, with graphics by Rebecca and Mike (see Comment), it was made in 1999.
