Oh, I love it.
Not too over the top, I'd definitely wear it. Whenever I notice I'm showing far too much chest I always just think "Oh, no problem, I'll put on a necklace."
Which is really quite a terrible problem, because the average necklace actually does little to save me from the depths of skankwhoredom.
So I've gained a love of big jewellery, mostly because something has to cover my body and it doesn't look like it's going to be my clothing.
