Unlike most other posters, I think that young Irish women dress particularly well. Most of my babysitters are better dressed than me. When I was starting out working in my early 20s, I had not a clue how to dress appropriately for work, and now I admire all the young women seem to 'get it.'
I was having lunch on my own yesterday, and seated at the next table was a young women amongst older colleagues. Over the course of their conversation (which I half-listened in to), I learned that she was in 2nd year in college, and was doing some unpaid work experience. She was impeccably groomed, beautifully and discreetly dressed, and she carried herself with modesty and confidence.
Most offices I go in to, the women are smartly dressed, nicely made up, and have neat tidy hair. Offices with dress codes always bring the standard up. In other offices, I have seen unshaven young(ish) men in slogan t-shirts, slurping cornflakes at their desks, with their trousers hanging down. I think generally women make more of an effort.
