Thank you all for responding.A few things really jumped out at me here.
First, I am not alone, and my returning number is -- in this community -- quite average or even low. So, whew! haha. (Don't we all love to find out we are normal?)
Second, returning is expected in the online shopping arena. I love what someone said about how returning 4 out of 5 things bought online is akin to putting back 4 out of 5 things tried on in a dressing room. That makes SO much sense to me.
Third, there is also something about YLF that may be a factor -- which several people pointed out. Because of YLF, I am probably buying more and trying new things (the Zara pleated top would be one obvious example) and this leads to returns. Also, in order to keep something, it has to be JUST RIGHT. YLF has helped me to raise the bar of my expectations, and this has led to returns too.
I'd still like to be less emotional in my buying (I really think I bought that grad dress because it was the first dress out of 20 that actually fit me, and it was on sale) and more on-target with my spending -- and reduce the returns that are because it was a bad purchase, but I feel better about the amount of returns I am making. And I have to say that I make returns immediately. I really want that credit, so I don't let things sit around, and that's better for the store and for me.
Thanks again, all. Really interesting discussion!
