I'm aware there in the placements I undertake, it may be appropriate for me to wear robes. I have posted about this before. I won't wear a cassock - it's just too much. Besides, I'd just feel like an extra from Harry Potter, though I do not have the stature to carry it off.
Talking of Harry Potter. The other day, while awaiting rescue from my bedroom, I had a clear out of my bedside cabinet. Among the items I came across was a photo taken of me at my graduation. It wasn't the professional one, but I think taken by my uncle. There I was doing an excellent impression of Harry Potter. All I needed was the scar on my forehead. The only reason my peers didn't make the connection was it was 1999 - Harry Potter hadn't gone viral, quite.
So, looks like a suit's the order of the day. Besides, if I wasn't already a graduate, technically I wouldn't be entitled to wear academic robes. Besides, if I were to wear them, my nearest and dearest (thanks Mum) would kill themselves laughing and wonder what was wrong with me!
