What is what do you call an alligator in a vest?

As an AI language model, I can state that there is no specific scientific or zoological term for an alligator in a vest. It is simply referred to as an alligator wearing a vest. However, one could use creative expressions like "dapper gator" or "stylish reptile" to describe an alligator in a vest. It should be noted that dressing up an alligator in clothing or accessories can be dangerous and is not recommended in real life.
