Is there a dress code in British hospitals?
Yes, there is. Don't show up in German sandals.
Don't dress in white only - they might mistake you for a cricket
player. Men should were smart shirt with short or rolled-up sleeves and don't wear a tie (deemed an infection risk). Wear decent trousers and clean leather shoes. Women can wear
both skirt and trousers, but again their outfit should not too casual and they must wear short sleeves.
Jeans are a not appropriate. White coats (Kittel) are also not permitted.
