I agree with Megan's answer above: starting a blog or a YouTube channel will be great start for you to find your unique selling point and what you are really able to offer!
With regards to fashion and your personality, it sounds like like PR (Public Relations) may be something you can look into. People who work in PR are very outgoing and part of the job is about networking, connecting with people and spreading the word about the company you are representing! So as mentioned, if you try blogging or a YouTube channel, you will be able to learn how to communicate with all sorts of individuals.
Also Eventbrite shows some free fashion-related events which you can attend with your parents or friends! You can see at first hand what it is like to be involved in the fashion industry, as well as take the opportunity to speak with people who work there. Networking and meeting people are so important when it comes to developing your next career, and your fun and outgoing personality will definitely benefit you!
