Another potential to get this idea started would be considering a collection of extravagant headdresses relating to seasonal changes and incorporating nature from each season into the pieces. The image above which is a sketch found on Pinterest reflects autumn quite clearly, with the leaves in the hair representing autumnal winds and rains, blowing the hair about with leaves falling off the trees and the colour palette is simply autumn like blues and whites would represent winter - looking into the semiotics and how we read colour would also be a really interesting look at this subject!
