Happy St. Patrick's Day! With festivities starting on Saturday thanks to Ireland's triumph in the Six Nations, followed by a free parade and festival in Trafalgar Square, there's still, surprisingly, plenty of energy left for tonight, even though it's, y'know, a Monday. So while the rivers in Chicago literally run green, let's shout out to this humble colour and remind ourselves that you can celebrate the Emerald Isle at any time of the year.

Used lightly, green's a great complimentary colour, and works well with grey and navy (which we'll assume makes up a decent part of your wardrobe). Try a dark green shirt, or tee to start, then add brighter greens to other outfits as accessories. Scroll down to shop the best green gear.
