These two combinations pose the same problem to me. On the left, the tie appears to have pindots, but the dots really create small squares that are basically the same size as the gingham pattern on the shirt. On the right, it looks like a grenadine. Like the tie on the left, the tie doesn't technically have a square pattern, but, visually, the weave effectively creates a small square pattern that mimics the pattern in the shirt.
I can see why when grabbing these ties, one could think that they don't have matching patterns with the shirts. Hell, the tie on the right is a solid. However, the visual effect of each just doesn't work for me with the shirts.
