I'm female, but I think I've heard before that some people think it's better to wear trousers to a TA interview, because it shows you're aware that the work can be quite physical and practical and that you're not afraid to get your hands dirty! (I got my present job wearing a dress, but then I was convinced I wouldn't get it due to not technically meeting one of the requirements, so I went in with a bit of a "won't get in anyway so what does it matter?" attitude. This time I want to get it right.) The other factor is that I haven't actually got very smart summer trousers - only wide linen ones. I can definitely look smarter in a skirt but don't want to look overdressed. Any thoughts?
