BEIJING, May 24 -- Costume jewelry is the easiest way to add charm, style and elegance. It is also the most economic fashion investment available in tough times.

    Key themes for next season's "bling bling" trends, as predicted by American jewelry brand Guess at a recent fashion show, are vintage-inspired styles mixed with a touch of romantic rock 'n' roll spirit.

    Also, look for statement sizes and gold plate tones like antique gold and burnished gold.

    While styling, don't be afraid to put layers upon layers, and enjoy the mix-and-match fun.

    Retro glamour is evoked in the multiple-strand tassel necklace featured above with rich texture in its mixed golden metal finishes and intricate braidings. The fringe treatments help add fluidity.

    Big, bold romantic rock 'n' roll pieces, like the bracelet on the model's wrist, are must-have fashion pieces throughout 2009. Both the bracelet and the necklace feature pearlized enamel stars to accentuate the romantic spirit of the collection.
