Because it FAILED.
The design was so simple, with these big plastic, rainbow reflecting beads. It looked like someone's reindition of the dress in the photo they advertised.
How could this have happened to me? I thought the plan was fool proof. The member on ebay has been selling dresses for years, and I read through the reviews. They all said "The dress was perfect! Exactly like the picture! I will buy from this person again!" Maybe my dress was the oddity?
I'm just glad that I made sure to go with a seller who guaranteed full money back. I wrote to the seller stating that I was not happy, and they were very cordial. They apologized and stood by their word of saying I can get a full refund. I'm shipping this baby back today.
(Sigh) The search for a dress is still on.
