his_j,
I really loved this poem (not in the least because I have my own obsession with belts). I think you chose some good concrete details to really help me see how *you* (the narrator) sees the belt.
Just a couple of suggestions (and if you do decide to revise this, I'd love to see the revision...please???):
Word choice: You make some excellent ones (I love the image of the belt "coiled" on the dresser) but I think you could shorten some of the lines and strengthen them by eliminating a few (unnecessary?) words (In the fifth line, scratch "simply" and possibly reword "nothing you pay attention to" as "unworthy of your attention" and making the sixth line redundant as you've already mentioned that the belt is only "useful in its purpose"?)
You might also consider using the commas on the 5th line as good places to break up that line, too.
But that's just my few little nitpicking observations. If they don't work for you, please, please ignore them and keep your poem intact. In all honesty, it really is good "as is"!
And I really, really hope to see a few more poems from you in the future...*giggles* Have you ever thought about gags? The poetry contest can always use a few talented writers!
