Yes you definitely can! Both brown and grey are neutral colors so they go well together. Even if they are light brown or dark brown shoes, they will still work. Most neutral colors will work together, but depending on your skin tone, it may vary. I have a grey coat and brown shoes, and i look damn good!
Yes
definitely black! :)
You can go either way.
You can wear black gloves with a brown coat, however it should be noted that many people wear gloves which match the color of the shoes they are wearing for a great fashion statement.
Not really, no. Black or charcoal grey would be much more appropriate.
Yes, you can wear grey pants with brown shoes. It might look a little odd, but if you have the right tones of grey and brown, it might end up looking very nice.
Probably black or grey something drak but not brown because i don't think it would look good
Either a black or white pair of shoes, or if there is more purple wear grey shoes; But no kicker shoes, those are ugly.
Brown,
most definitely
Ew no
Grey? do you mean why did they wear grey? Brown and black were the primary colors of clothing in this time and no grey.
