On Ebay you can get everything from the top-of-the-line shimmery Alka Vora skirts to the more vintage floral styles available (also cheaper!). Decide on a general color or pattern type that works for you and then start sifting through the myriad of skirts available! Don't forget to accessorize with piles of jewelry and a flowing top!
