What is the difference between an oxford and a derby?

An oxford has closed lacing, where the eyelet panels are stitched under the vamp. It reads more formal. A derby has open lacing sitting on top of the vamp, giving a slightly wider fit and a marginally less formal look.

Which dress shoe is correct for a Malaysian wedding?

A black or dark brown oxford or derby is appropriate for most Malaysian weddings. If you are the groom and wearing a tuxedo, choose a plain black oxford with minimal detailing.

How do I stop dress shoes creasing?

Use shoe trees after every wear, rotate between pairs rather than wearing the same shoes daily, and use a shoe horn to avoid crushing the heel counter. Some creasing across the vamp is normal and unavoidable in leather.

Can I wear brown dress shoes with a navy suit?

Yes, and it is one of the strongest combinations in menswear. Dark brown or coffee leather with navy tailoring looks considered rather than default. Reserve black for the most formal occasions.

How do I care for leather dress shoes in Malaysian humidity?

Let them dry naturally away from direct heat if they get wet, condition the leather every few months to stop it drying out, and store them with shoe trees in a ventilated space rather than a sealed box.
