This one isn't going to win any points for fashion design in my opinion but as an investment it might be pretty smart considering recent gold prices. Yesterday Japan's largest bullion house showed off a gleaming gown which is covered with hundreds of gold coins. Pity the poor model wearing it. Mayuka, the model weighs around 110 pounds and the dress is close to 18 pounds. The dress was made using 325 Austrian gold coins issued to commemorate the Vienna Philharmonic and is valued at $275,000. There are no plans to offer the dress for sale.
