If your wedding is in December or January of next year, (OR you're color scheme is largely white or burgundy), you need to be shopping on December 26th. Buy decor, buy ornaments to give as favors,(or use as place cards or centerpieces), buy those little white lights to put, like everywhere. Find sparkly stuff for your bridal party, ribbon to embellish your invites, and candles for.....everywhere. But don't buy anything that sings, moves or blows confetti. No one wants to see that.
