Roots of Wearing Green on St. Patrick’s Day
March 17 is St. Patrick’s Day. It doesn’t matter that St. Patrick was born in Britain. Never mind that the traditions of celebrating St. Patrick’s Day came back to Ireland over the pond as a great spring tourism marketing opportunity. On St. Patrick’s Day, the Irish-American community celebrates with parades and parties, and it is advisable for kids to wear something green to school to avoid being pinched. Not always does mama have green duct tape handy – Alaska’s solution to fixing whatever is fixable – to savor the kid who refused to wear green.
Even when your ancestors were not Irish, you may want/have to wear emerald that day. Why? Just because there is a great Irish community in your town; you are invited by your friends who have Irish ancestors, are Irish or celebrate everything; someone at the office is throwing an Irish coffee break – you name it. The big question is: How to wear green for St. Patrick’s Day without looking costumed.
In other words, how to wear green in a posh chic way, but keep people guessing whether it’s because of the occasion or just because – well green is a great color.
Shop Your Closet for a Work-Appropriate Green Look
The day has become a great commercial thing in recent years starting with meadow-green cupcakes to entire clothing collections. Even if you are not into it, you may want to fit in the spirit of the day as a courtesy to your colleagues, friends or who ever takes the effort of throwing a party and/or decorating for St. Patrick’s Day. The easiest way is to create an outfit with one green item like the St. Patrick’s Day outfit ideas in the list below.
- Style a monochromatic outfit in various shades of green like a mint green shirt under a hunter-green sheath, and Kelly green pumps.
- A plaid shirt that has green as one of its colors with a green or other color of the plaid skirt/pants and neutral pumps.
- Green work dress with pearls and neutral pumps.
- Wear a shirt or top with a green print with neutral color pants/skirt and blazer.
- A denim skirt plus plaid shirt with green sweater combination makes a nice work outfit for a casual office. The layering helps to stay warm in a thin cotton button-down shirt. More on layering for thermal comfort.

What Not to Wear on St. Patrick’s Day
A head-to-toe meadow-green outfit never looks great, not even on St. Patrick’s day! It is just plain ridiculous at any age, unless it’s a sport uniform. Unless you want to wear a costume, go with one meadow green item. A green dress is great, but either color-block your shoes (see featured photo) or go for nude.
