Get rid of those clothes - give to someone who needs them and know that you NEVER will again.

I worked in an office, so had to dress appropriately. When I had to retire in 2006, I got rid of 99% of the clothes and high-heeled shoes, since I would never need them again. It wasn't a weight issue as my weight never fluctuates more than 5lbs either way, but my retired and relaxed life no longer called for suits and dresses and high heels. I was more than happy to give them to someone who would get use out of them - while they were still in style too. And the few items I kept - I've worn one of the dresses once, and a suit once - the dress slacks??? - never!
