Cambo... don't suppose you are the young lady who stayed in the Express Inn the day before aptitude testing !? If so, I may have shared the courtesy van with you. Probably write back and say you're a bloke now !! Appropriate clothing in my eyes is the cliche "Smart Casual". Shouldn't think they'd take too much notice - as said they're not expecting suits. I'm sure this stage is just to determine how well you interact and cooperate with others. They'll probably be more likely to judge appearance in the final interview. Right... I'm off to get my 'lamps' tested at the opticians.....
Good luck,
Bleep.
