What are your most frequent reasons for purging an item from your wardrobe?

In a recent purge, I went through the instructive exercise of ascribing a reason for each of the rejects. I was surprised at my discoveries!

Lessons learned:
1. Only buy what I really love and cannot live without! (resist the sales...)
2. Don't accept less-than-perfect fit

Of 30 purged items (about 10% of my wardrobe), the top three reasons were:

1. Bored with it - 30% (a perfectly OK reason by me)
2. "Not me" / never loved it / bought mainly for versatility - 25%
3. Poor fit - 25% (this shocked me because most of these were poor fit to begin with; only a few were items that I "grew out of")

The remaining 20% were reasons of:
worn out
poor quality
dated

Some more interesting statistics from the items purged:

Number of wears:
-less than 5 - 30% (another shocker - these were almost exclusively for the two reasons of poor fit and not loving it)
-about 10 - 30%
-20 to 40 - 30%
-remaining 10% - 60 or more

Age of item purged:
-less than one year - 30%
-1 to 3 years - 45%
-4 years or more - 25%

The surprise here is that the age distribution of rejects approximately reflects the age of my wardrobe as a whole - I would have expected the purge to be weighted more toward older items. But again, the items purged after less than a year were mostly for reasons of fit and "never really loved it."

Thanks, YLF, for helping me hone my buying habits and transform my wardrobe!
