do you actually need to speak?
I want to give introduction at a fashion show in a competition, I need to introduce myself in a sparking way. How do I need to prepare it?
Keep it simple. You never hear professional fashion shows being introduced with lengthy speeches as this would just bore the guests, as they are there to see the clothes and the models.
Just thank everyone that is taking part, say how excited you are to show off all the amazing designs, and wish everyone a great show!
