Buy it because it fits?

I have very few hard and fast rules when it comes to jewelry.  One of my rules is that if I find a piece of jewelry that I want to buy but I can make it, then I am required to at least attempt to make it.  And secondly, if I find a bracelet (that I can't make) that actually fits my child-size wrists then I buy it!  Especially if the price is right.  I hit the Nordstrom Rack clearance section this week (at a minimum, this is a quarterly event) and discovered this plastic green cuff.  It fit perfectly, and it was under $10.  Sold!  But really?  A plastic green cuff?  Today I am questioning the thought process that went into this purchase.  I am thinking that I should add one more important criteria to my list of questions...must love it.  But here I waiver.  It was under ten bucks.  So what if I only have occasion to wear this funky thing once or twice?  :)  By the way, the chain link bracelet was a gift from my friend Kristin for my birthday last year, love it!
