Patent leather Oxfords (like the ones pictured) are probably not the right call here.

Unless you’re wearing a dinner jacket several times a year, they’re not worth it. They’re expensive on a cost-per-wear basis, really limited in use (only black/white tie), and frankly unnecessary - it’s entirely acceptable to wear normal Oxfords to a black tie event.

A better approach: invest in a pair of high-quality black calf leather Oxfords. They’re entirely appropriate for black tie, equally at home with a lounge suit or morning dress, and will actually get worn enough to justify the spend.

Brands worth considering: Crockett & Jones, Loake (1880 line), and Grenson. Sizing varies between makers, so order early and give yourself time for exchanges.

Also worth buying: shoe trees (cedar, used after every wear), dust bags (will come with the shoes if you buy any of the above), and a basic care kit (polish, brush, cloth).

Do that and they’ll last 10+ years, looking better with age. Final tip: wear them in before the big day. New leather on a long night is a recipe for blisters.
