New shoes! New shoes!

I got a new pair of Land's End shoes recently (adorable, right?)... actually, I got a pair for Christmas in the true navy color and they were too big. Instead of sending them back to Land's End to return, we realized that Sear's carries Land's End products and accepts mail-order returns and exchanges. Well, then there is no shipping charge to send them back! So I went to the nearby Sear's Grand store a couple weeks ago but they didn't have any in my size. Last weekend, I went to a regular Sear's store and not only did they have my size, but the shoes were $15 cheaper! I bought a pair in black, though, because it was either that or flame orange. And I thought I liked the black best of all anyway. Well, I told my mother about this cost savings and suddenly she wanted a pair. So we went out this weekend, to a different Sears, and she got a pair. Plus, they had my size in the true navy. Now I have a pair in black and a pair in true navy and I just can't decide which to keep and which to return. I'm trying to figure out which color would go with more so I'm basically trying on every pair of pants I own to see which I like best! It's tough being a woman!
