Cool Belt from Monday

You'll never guess where I got this belt, in fact, please do.  I'll tell you the answer tomorrow (or the next time I remember to get on here).  
Anyway, I was digging through my closet and found these olive green corduroy pants.  Given that they're a size 12 and I'm NOW sort of a 12/14, I haven't been able to wear them in a while.  Well, when I tried them on, they fit, but fit too short.  I let the hem out and used some iron-on tape to redo the hem.  In figuring out what to wear with the cords, I remembered that this canvas belt has some olive green and built the rest of the outfit around it.  I added the black sweater for warmth because it was 31F when I went to walk Bella yesterday morning.  
Do you find yourself composing outfits based on an accessory?
