I will be doing archival research in London this summer. What would be appropriate to wear in such a setting? I've done similar research in the US and the dress of the other researchers ranged from Crocs and cargo shorts to basic suit. I wore a tweed jacket, OCBD, tie and trousers most days. However, that was in the winter. I'm a 30-something social sciences PhD student trying to differentiate myself from the pack, with a fairly small selection of nice clothes and an even smaller budget to add new items. However, I'll keep my eye open on B&S for anything suggested that I don't have. Thanks in advance.
