Wouldn't touch anything navy; its a #menswear fad like those camouflage fabric blogger short blazers back in '08. The only acceptable navy shoes are navy suede drivers. OE2 is great, oxblood and black both works well. I would skip the Italian Oxford since the adelaide pattern by Vass is already goofy. Not sure how French oxford would look since there's no toe pattern weighing down on the balmoral line; and being a new pattern, how it will look stretched to a wide/G or double wide/F fitting. Black will always look good with mid to dark colored suits in shades of gray and navy.
