@merv49 My guess is you can pair those similarly to tan grain. I think they'd look particularly good with off-white chinos. They'd also work with denim. It's no bad thing to have some "statement" shoes in one's collection.
@mogili222 Do you know what last the Peals are on? If not, why not ask Brooks Bros? If they are on the 335, then you will know what size to go for in the Skyes.
Personally, I prefer the plain cap of the Peals. It makes them a little more versatile, although it sounds like your intended use is primarily informal.
@Rstldr loafers need to start snug as they have no means of being tightened. Your toes seem to splay laterally whereas the last you have chosen angles in. It's possible they will stretch - especially if they are unlined - but visually from above they don't look like a great match to your feet.
