Clothing..how much do we really need?

I can't remember exactly when it happened but I went from owning  4 pairs of jeans, 10 tops, and 5 pairs of shoes to having multiple closets and dressers burgeoning with clothing!    It's not that I keep clothing forever... as a matter of fact in the pre recession days I gave regularly to clothing drives and local charities.   It all had to do with excess disposable income burning a hole in my wallet.  Many times I went shopping for clothes in such a hurry that I pulled things off the rack without even trying them on.  My husband often joked that my charities got clothing with the tags still on.  So now I ask..what is the purpose of all of this clothing?
As a child from a lower income family I did not own many articles of clothing.  I had 7 outfits per season, one for each day of the week. My mother did laundry once a week and my outfits were ready to go. Needless to say, they were all very well worn.   Today, I am certain, that based on the clothing that I own, I could wear a different outfit for each day of the year!  Seriously, I counted my shoes the other day.. 78 pairs of shoes.  I have 15 winter coats as well as 15 bathing suits...  I am not buying another article of clothing for the rest of my life.
