Seeing Double?

So, as most of you HB collector girls know, this is a Hotbuys Dress, which one person is selling for sixty stardollars:

However, at Tingeling, you can buy the Balloon Tube Dress for only seven dollars, and they look a LOT alike.

Why did Stardoll create two dresses that look so much alike? It's rediculous. If you are a HBs collecter, you obviously would want the HBs version because it says Hotbuys on the tag. If your in it for the fashion, go for the Tingeling Balloon Tube Dress. (:

Also, I got this picture from Stardoll's Most Wanted Blog. Why is Stardoll making look-alikes? Too lazy to think of new things?
