OMG the colour of those dark cherry brogues, can I ask what you intend to wear them with? Are they for work or just socialising? i had red oxfords back in 1980-81 and I only ever wore them with black trousers or black suits inner city post punk fashion or was it bleak romantic?
I would not even try to match a belt with them.
Personally the colour does limit your choices with what you can wear them with. British Khaki? Midnight blue or black? They certainly are head turners and not for the faint hearted.
I would attempt to polish them with black like the old Churchs "cherry reds". It will tone them down a bit and give them an awesome antiqued effect. But of course I forgot they are shell. Will that take colour?
