Should I buy a t-shirt that says "Pretty and Lucky" for St. Patty's Day? - what shirt to wear with kilt

I hope that the tables in a restaurant on the Irish theme, and we dress for St. Patty day tomorrow.

I still have a T-shirt to use with my lap, but today I found a brown T-shirt at Wal-Mart with an image of the type of care, colors and large letters that read: "Pretty" and " Lucky. "

Only the small size of the left on the shelves, and is a little tight, but not so bad. It is 13 U.S. dollars, which is more than I wanted to go, but I need something before lunch tomorrow.

The biggest problem I have is with him that I do not think that I was vain.

What do you think? Do I just have fun and buy a T-shirt?

Thank you! Happy Green Day!
