London IB Dress Code

yup there is a saying 'no brown in town'

Pre covid the uniform was basically a Navy suit (I liked wearing side tabs on my trousers, belts are less of a thing), white or blue business shirt with silver cufflinks, and black oxford shoes. Fairly conservative, but pretty easy to dress. Rarely a tie, but always had one on hand.

I would have been laughed at if I wore brown shoes, "no brown in town" is real

No brown in town, and no monk straps... especially no monk straps.

It is true that you won't see brown shoes in London, at least not in most cases. I can't remember I have seen brown shoes in my team.
Some people do go out of the ordinary and have unique accessories like a tie bar, or unique cuff links. But that is about it.
Suspenders are not as common, but every once in a while you will see a guy wearing them, it is rare though.

Current personal dress code: blue chino pants, running shoes, white shirt. I don’t have a tie or suit jacket in the office. Before covid would probably be suits no tie 

crap ive been wearing brown shoes for my internship the whole time...- never knew about this xD

Why `no monk straps (single monk straps, that is)?
