Checked or plaid?

I ended Wednesday's post with a question about "checked" versus "plaid".  So, I looked it up.  Checked is a pattern of squares.  Plaid consists of crossing bands or stripes of color.  According to those definitions, this guy would be wearing a cool skinny plaid tie and holding a unique plaid phone -

Now is this next guy wearing a checked or plaid shirt? 

 

I'm leaning toward plaid.  But whatever it is, I love this bold combination with the argyle (just to throw in another pattern) sweater vest.



And he's wearing plaid shoes!
