I could see from your OP, petra what you were talking about, but I was puzzled about the thread title. It does, after all, ask "what are you wearing?", so you shouldn't really be surprised that people have answered the question .
I rarely wear make-up these days, only if I'm going out somewhere (and I don't mean to Sainsbury - that calls for just a touch of lippy and eyebrow pencil!). If I knew I was going to appear on TV then yes, definitely, I would make sure I was presentable, but otherwise it's comfort all the way .
I do wonder, though, when I see people looking, er, a little 'relaxed' on TV, whether they have been told to dress down, even given a list of suggested clothing. Surely they wouldn't actually choose to be in front of millions of people looking so dowdy or underdressed?
