Windchime, I think there are a couple of reasons this can happen for me. Sometimes if it's a newer style I don't have the right support act for the item in the first season, try as I may to find it. Then all of a sudden I find the complements it needs and I start to wear it. Sometimes, the item is a "style stretcher" and it just makes me a bit uncomfortable at first -- I felt like that about my first pair of white jeans, for example, and I had to force myself to wear them the first few times... but now I wear them constantly! Sometimes the weather doesn't cooperate or expected occasions don't materialize so I just don't get as many opportunities as expected to wear it in the first year.
Also, if I'm tempted to get rid of something that I still like a lot, I sometimes look at Angie's "how to wear it" type posts and get enough inspiration to create some new outfits.
Janet, I know, right? These closets are HUGE!! But weirdly, no drawers, and hardly any "full length" space for dresses, etc. I'm not complaining, though. A trip to Ikea solved those issues. I also have a TON of mirrors in this house! An entire wall in our bedroom, plus big bathroom mirrors, a mirror in the front entrance, and a big mirror in the hallway. I see myself coming and going. It's weird living with someone else's decor and "stuff" but also really interesting!
