These days, aside from your precious stones (gems and diamonds), there is very little that is "real." This is not to say we're wearing costume jewelry, but we are wearing more disposable trends. These styles are made from lesser quality metals, follow trends of the season, and rarely remain in your taste palette for longer than a year. For this reason, don't feel bad about buying jewelry that may tarnish or break easily.
Forever21, Target, and many other "bargain" stores offer a good variety of this type of jewelry for less that $10 a piece that you might just find to fit your fancy. I recently purchased this.

It incorporates my random recent obsession with bird and flower charms, fondness for anything with layers of "dangling" things, and a move from preferring silver to gold. I'm noticing a lot of layered jewelry including mixed colors and textures, varying between metals and even pearls.

I'm a big fan of the vintage look of the jewelry I'm seeing in stores lately. What do they go with? Anything, really. You don't have to feel like these necklaces will only go with a ruffled, empire-waisted blouse and skirt. Pair it with pearl stud earrings, a feminine t-shirt, and jeans. It's all about balance. Just beware of wearing a statement necklace like this with a pair of dramatic earrings or a neckline that speaks for itself.
