What color is your tie? Wear a square that's roughly in that color range, or just as long it isn't clashing horribly, but also make sure it's not too similar. Today I wore a dark green pocket square with a brown cashmere tie.
Oops, that's obviously a vital piece of information I forgot to mention: I was planning on wearing a navy or black grenadine.
First of all: Why is this thread so dead silent?
Just had to compile some of the colour combos from S/S '14 from Berg & Berg:
I think the edges are very interesting in this compilation.. It seems they have a few schemes (rasberry, mustard/orange and turquoise) that are general throughout the large patterned collection, but then the central colours have such a huge variety!! It's not as large as the Drake's selection, but then neither are the prices (I'm not gonna pay 65£ for a PS before I have finished school!)
