Lucky St. Patrick's Day Men's T-Shirt Size Large L Leprechaun Suit Irish Green. You almost have to wear something like this on St. Patrick’s Day. The fact that it is a Lucky Tee Shirt, the fact that the front is a leprechaun suit makes it doubly so. It is the perfect green and I would highly recommend a dark green blazer to get you there and back from the party. I think it would offset the leprechaun vest very nicely. I am recently at the age of, very old, so we will leave it at that found out I am about 73% Irish. How lucky am I ??? You too could be Irish for one day in March. This is suitable for year-round wearing, but it really should be a staple in your closet for many occasions. That might include winning the lottery and going to collect your check! I am not convinced this was weren’t even once, but it is like new condition .
