Barriers to Minimising your Wardrobe

Hi,
I am currently working on the beginning of a program to help women (20-30yrs old) to minimise their wardrobe, and i was wondering if there are any studies that i could read around this subject. I'm particularly interested in the barriers and benefits on why people keep and store their clothing instead of donating or recycling.
Also, if there is studies on helping people to reduce their purchasing of clothing as well, so i can begin to guide them through a process of a more manageable wardrobe system.
Thank you for your help
Dani
