Thanks—I debated about wearing loafers with the socks kind of for this reason (though not specifically). I dunno. Thanks for the feedback.
It's Kent Wang's Carta Marina pocket square.
I like the socks and the loafers (the snuff suede looks great with the colors in the socks), but I think a looser trouser would look better (hiding a little more of the sock).
EDIT: It's also all cold colors on top of all warm colors, which can be tricky. I think some warmth above the waist might help.
