Okay I'm a bit of a shoe nut... over 60 pairs on hand now.
Here are a couple styles that I think are dressed up without being too formal.
Sorry for links to instagram... i'm not sure how to show just the image.
Moc-toe derbys like the AE Bradley... this is a pair i thrifted, stripped and re-coloured.
Desert Boots / Chukkas
These are
suede Rancourts, but Clarks offer lots of styles for a reasonable price (but without a moc-toe).
Believe it or not, but wingtips are a more 'casual' style... especially long-wing gunboat derby's such as
these vintage Florsheims.
