complicated job interview outfit help.

[HoneyDuke]

I have an interview for a school outreach job at a university in a couple of weeks.

Group assessment, then a presentation to some yr 10 students then a formal interview.

I have a purple short sleeved shift I've worn successfully to interviews brfore, but I'm worried it will be too formal for presenting to the school kids.

Good excuse for a new dress maybe?

By all means buy a new dress, but formal is good when presenting to Y10.

I am a teacher, and would always rather be too smart than too informal at interviews.
