I found this tennis ball Limoge trinket box on Etsy. The shop is "Temple of Vintage." The cost is $24 plus shipping. This would be a nice item to keep on your dresser with a special piece of jewelry inside.
Isn't this a lovely Swarovski crystal evening bag? It is on the www.Kaboodle.com website. It was originally $995 but on the Madisonavemall.com it is on sale for $599. This evening bag also has an optional gold chain strap. This crystal tennis ball evening bag would really add whimsy to your LBD and would also be a great conversation item.
