Do or Don't? Arm Bands

It's no secret that I am a fan of Catbird and all of the lovely designers whose jewelry they sell at their store.  I am on their site at least once a day scouring for new finds and mentally rearranging my wishlists.  Yesterday I saw this The Bearhead Factory Arm Band under their new items and it made me stop in my tracks. Are arm bands coming back? There was a time when they were ultra cool - made popular by people on opposite ends of the style spectrum like Sienna Miller and Pamela Anderson.  Wow, never thought I'd mention Pamela Anderson on this blog, but there you have it.

Tell me, so you think arm bands are a Do or a Don't? Are they rocker-chic or too tough/grunge to be cool?
