Pocket squares, however many you stuff into a breast pocket, count as one pattern towards your total!
Socks do not count.
Additional items like overcoats, scarves & hats do not count but are welcome if you can integrate them coherently into your post.
For those of you unable or unwilling to go the full four, please try for your best three pattern combos and post here, they will not be entered into the vote but may serve as inspiration/examples of coherence.
Any more questions...?
