If you are going to own one suit, get thee to Brooks Brothers.

You're looking for the Navy 2 button suit. Not three and god forbid 4 button. Black lace up Oxfords or toe caps. White point collar shirt, button downs are for sportcoats.

If you don't have a BB around you are looking for Hart Shaefner Marx or Hickey Freeman.

Don't take chances and don't try to make a fashion statement.

Black suits are not business appropriate.
