I know too many people who buy a lot of stuff emotionally or "on sale" and it sits in their closets only to collect dust or be given away eventually. Somewhere I figured out that if I only buy what I REALLY LOVE then it all eventually works!
For example...I bought this suede fringed hippy vest almost 2 years ago from Fossil.com. I had to have it (I guess it brought back pleasant memories of my hippy days). I have only worn it once! However check it out...I just bought a tunic I love and had some bangles that I have had for 20 years and a seed necklace that I bought 10 years ago...awesome outfit! Each item is something I LOVED.
The second outfit is a leopard jacket I bought years ago and LOVE. Never could part with it. I bought this belt from Anthropologie this summer because I LOVED it. The skirt and boots were fall finds and presto...I love this outfit with black tights and a black ribbed t-neck!
Only buy what you absolutely love and take back everything else!
