Hello! I (20F) have a summer internship in the southwest U.S. at a national lab and my manager said the dress code will be casual after the first week. What would you consider to be casual, and what recommendations do you have for a hot climate? (I know the ac will probably be blasting lol but I also don’t want to be too uncomfortable outside). I have dress slacks and blouses, but I don’t really know what the step down from that is. Dark jeans? I’m seeing mixed opinion and mostly suggestions for men online.
