Definitely not rhinestone cowboy.
Haven't read the other comments, pardon if I repeat other advice.
I think these would be the extra "oomph" element to an outfit. Not too "oomph-y" though - subtle and sophisticated. That is, as you'd normally wear this cut of jeans, but with the pearls and rough edge, the jeans themselves add the bit of extra.
One more try - I'm tongue-tied this morning: Don't add to the jeans, the jeans themselves add to the outfit.
Hope that helps?!?
