This year's National Pro-Life T-shirt Day is tomorrow: Tuesday, Apr 27. Wear your pro-life gear as a witness to your convictions. I bought my family's T's at Heritage House where a wide selection is available. You get to choose the design and can even have one added to the back for a little extra.
If you need to wear something dressier on that day, consider pro-life jewelry. Cute "Precious Feet" and "Precious Hands" pins, made to match a 10-week old unborn baby's in size and shape, are a popular option. Lots more here.
