Out of those I would go with the Dylan's, the slimmer sole will work better with a suit.
Sorry for the post about shoes in this section of the forum, I just thought that this section get's a lot more attention so more likely to get feedback.
I'm going to a wedding in December, and I'm wearing a navy suit.

I'm 99% sure this is the same suit I own.
The only problem I have is that I just can't decide on a pair of shoes for the occasion. I have two options in mind
1) Grenson Dylan Tan - http://www.grenson.co.uk/en_gb/shop/dylan-563
2) Loake Ashby Tan - Loake English shoes
I know the two options are fairly similar, but which pair would you go for? I am also open to any other suggestions, just keep in mind my limit is £200

Agree with Will, the Loakes aren't really formal shoes imo
