I know they'll love you, how could they not?? But I remembered another interview tip - Sit leaned back (not slouching), it shows more confidence than leaning forward.
Confidence balanced with humility...
I like to ask tough questions when interviewing. Like the one they call the killer question: So, tell me a little about yourself... More of a request than a question, usually just a good way to get the ball rolling.

Keep it short, sweet and positive.
Example answer for you might be something like: "I'm a hard worker, my strongest skills are .... , I know a lot about fashion and business and supervising. I'd say my key accomplishments are ... How about you?"
Ending with a question, ball in their court showing your involvement & enthusiasm.

If they ask about your worst boss or job or biggest challenge ever in a job, keep it light - stay positive. Like, "I did have a manager who put a lot of strict deadlines, and that was a huge challenge, but I actually succeeded, stepped up to the challenge and got the job done, and it ended up being a good experience."

Or if they ask for your strengths and weaknesses... strengths are easy but weaknesses are tough. And people who tell me too much probably aren't going to get the job.

For you - if they ask a weakness, with what I know of you, I would say, "I can get impatient with projects not happening fast enough, honestly. I want to stay busy and creative. For example, my career growth, I want to get in there, work hard, be a part of the fashion industry - it's always growing, changing, and that is really exciting to me."

And stay positive about current job and reasons for leaving... Don't tell all lol...

Sorry if I'm telling you things you already know! Just excited for you, wish I could drive you there, wait outside and then scream our heads off in the car after - windows up of course lol!!! Love ya
