Alice saw a rabbit that was different from any rabbit she had ever seen before. The rabbit had several unique characteristics that caught Alice's attention.

Appearance:
The rabbit was not like any normal rabbit. It stood upright on its hind legs, just like a human. It was also much larger than an ordinary rabbit, almost the size of a small child. The rabbit had a sleek and shiny fur coat, which was a vibrant shade of blue. This striking color made it stand out from its surroundings and caught Alice's eye immediately.

Clothing:
What made the rabbit even more extraordinary was the fact that it was wearing clothes. It had on a smartly tailored waistcoat, which was a bright shade of yellow. The waistcoat had large pockets, and Alice could see a pocket watch sticking out from one of them. The watch was made of gold, and its hands were moving rapidly, as if the rabbit was in a great hurry.

Behavior:
Another peculiar characteristic of the rabbit was its behavior. It seemed to be in a constant state of panic and kept checking the watch in its pocket. It muttered to itself and occasionally glanced around nervously, as if it was afraid of being late for something important. The rabbit's behavior was so frantic and unusual that it fascinated Alice, and she couldn't help but follow it to see where it was going.

Conclusion:
In summary, the rabbit that Alice saw was different from any ordinary rabbit. Its unique appearance, including standing upright, its blue fur coat, and the fact that it was wearing clothes, made it stand out. Additionally, its behavior of constantly checking a pocket watch and appearing panicked added to its peculiarity. Alice's encounter with this extraordinary rabbit marked the beginning of her whimsical and magical journey in Wonderland.
