Congrats on getting the interview with Strathclyde! When I log onto track it says 'Interview' next to the university, so might change to that eventually? Do you know what to expect from the interview process yet?
I was thinking the same thing about what to wear! I'm not much of a suit person either, so I guess whatever you find comfortable whilst still looking professional is good. I think I'm going to go for a plain knee length dress, with either a blazer or cardigan - will have to try them on before I decide lol!
