Upon receiving my first pair of double monk shoes (in brown suede) I got to thinking about the regional differences in what is acceptable to wear to work in a formal business environment. I work in banking in the UK and initially I thought I may be able to pull of double monks but now I'm not so sure they're appropriate (rather than just being contrary to my personal style). I just don't think I've ever seen anyone wearing such a shoe in my industry and region. Can you gentlemen think of other examples of things that aren't appropriate in your region (rather than environment)? I can certainly think of other regional differences. For instance, it is perfectly acceptable for any male member of staff in the UK to wear a French cuff shirt, no matter how junior. I have heard that this would be seen as dandyish in the US. But it is a standard shirt option here, whether at a high street shop or Turnbull and Asser. I also believe stripes are more appropriate for business here than elsewhere. Generally speaking it would also not be appropriate to wear a button down collar here in a formal environment. Whereas the president could do it and all would be fine. Black suits are of course another example. De rigeur in Asia but for funeral directors in the west. I would be interested to hear of other variations depending on where you live.
