I have the book, need to apply the principles. Last night I really took a hard look at the new items I just purchased because it's a lot easier and more cost effective to not add the item to my wardrobe than purge later. I'm (a little regretfully) returning a few extra pair of shoes and items that I'm not 100% in love with. I'm struggling with the Halogen navy cashmere wrap. It's beautiful but I don't wear a lot of navy. I keep putting it in the return pile only to pull it out. Lol!
I totally do this. I have the hardest time returning things sometimes because of it. Sometimes I return the things I know I don't want right away, and wait a week on the things I'm unsure of. The good news is, even if you return and decide you want it later, chances are you can get the same thing or something similar at that time.
