I'm actually looking to get a pair of brown meermins as well, if you already have four blacks I'd say you should invest in some browns. Brown suede could work but I usually prefer slimmer lasts when it comes to suede and with what meemin offers I'd go with this one https://www.meermin.es/articulo.php?idArt=4719#. But I mean if you're dead set on suede you can get them there too or on loakes.
BTW where do you get your loakes/allen edmonds?
Ended up picking up the black lowndes for ~$420 will get some brown shoes later
Loakes were from pediwear though i heard theyve stopped shipping to australia
AEs were seconds from ebay when our dollar was decent
