What it is: A geometric pattern consisting of perpendicular lines, resembling the likes of the board game classics. (Think checkers, tic-tac-toe, bingo, etc.)
Why it's RAAD: You've officially been given the green light to really amp up your linear love affair. Layer those lines on like the walking optical illusion you are!
How to wear it: This is your opportunity to mix perpendicular and parallel lines in one look. You can take your Breton striped tee and tuck it into a grid-like pencil skirt. Or layer a striped blazer on top of a checkered blouse with some ankle skinnies. Make sure to have a solid neutral color in the mix. We don't need people falling over in a trance.
