Be natural and imply that you love this job! The most taboo is nervousness. I once attended a similar major, and the teacher suggested that I only wear a simple T-shirt, which is simple and generous. For the audition clothes, many magazines have introduced them, such as Shanghai Clothing. The action must not be too big, just a proper modification. Don't forget to pronounce words clearly, don't repeat sentences, and smile with confidence. You will succeed!

Good luck! You can do it!
