For holiday parties, consider something shiny, or glitzy or sparkly or beaded or velvet. Start with black.  Add a sparkly shoe, a red bag. Accessorize with some dazzling and festive earrings or bangles. Have fun, relax, don't take yourself too seriously, and celebrate.  A word of caution, though; keep your outfit appropriate, making sure to avoid major cleavage or see-through tops.  Add red lipstick and nails...and you're perfect for your holiday gathering.
