Each outfit in this series crafted from paper by students in Estonia represents a different month (+ slideshow).
"It was a very quick course, so students had two weeks for research and then two weeks to test and execute real costumes," Ilison told Dezeen.
This photo set styled by Ilison was used to create a calendar for paper brand Antalis.
"I selected best 12 outfits from 24 participators, then I proposed the idea of a calendar to Antalis and they liked it," said Ilison. "Later we selected and decided which photo would portray which month."
The first two wintery pieces were made from white sheets, with January's design comprising layers of circular sections with strips cut out.
For the second, long tubes crossed the body to form a scuptural dress while shorter rolls were stacked into a headpiece.
Moving into Spring, floral shapes adorned outfits as geometric seed pods and then scrunched up pink petals.
July's offering saw the material edged in red, looped tightly back and forth to create giant ruffles similar to Elizabethan neck pieces.
Colours became more somber on the autumnal garments, particularly the collection of brown shapes built up around the body and extended over the head that looked like leaves ready to fall.
For December reams of colourful ribbon-like strips splayed from the shoulders and curled up by the ends, with some tied in a bow at the neck.
To see more paper fashion, take a look at a Royal College of Art graduate collection that features a dress that expands as you move and a concertinaed handbag.
