Would it be disrespectful to wear dream catcher earrings?

I have been reading about cultural appropriation (sp?) and most of the articles said that random people wearing things like headdresses is disrespectful towards traditions of certain tribes (which makes sense), but I didn't see anything about wearing Native American jewelry like dream catcher earrings. I was just wondering if I could get some opinions on it, preferably from someone who knows what they are talking about.
