I would say that my clothes change my mood more than my mood changes my clothes.

I really am attached to most of my clothes, so I always get a bit excited when I get my next outfit in the morning, or if I remember what it was from the night before. For me, the biggest benefit is that it has stopped me from "saving" stuff. I have this annoying habit of saying "this is too good to wear day-to-day" and then it sits in my closet. I actually wear almost everything now.
It also seems to cut down on wash, and wear, because everything gets worn equally, and you end up with big piles of each color. I'm sure in a few years when everything dies at the same time I will have a different view.
I was a bit worried in posting my strategies that people would think I was crazy. I'm glad that people are keeping those kinds of thoughts to themselves if they have them

). For me, it has made pulling on a skirt and a blouse easier than jeans, because with jeans I have to find everything- the jeans, the top, etc. Getting ready to go to the home improvement store takes longer than getting ready for work, and I like that. It puts me in a good mood for starting my work day.
