Let your Tshirt share what Easter Eggs mean for you as a Christian.
The hard shell represents the sealed tomb and the opening of the hollow egg to find nothing inside represents Jesus’ resurrection from the dead.
Easter eggs also symbolize the resurrection of Jesus Christ and the new life we as Christians receive through him!

John 20:1-9 NIV
Early on the first day of the week, while it was still dark, Mary Magdalene went to the tomb and saw that the stone had been removed from the entrance. So she came running to Simon Peter and the other disciple, the one Jesus loved, and said, “They have taken the Lord out of the tomb, and we don’t know where they have put him!”
So Peter and the other disciple started for the tomb. Both were running, but the other disciple outran Peter and reached the tomb first. He bent over and looked in at the strips of linen lying there but did not go in. Then Simon Peter came along behind him and went straight into the tomb. He saw the strips of linen lying there, as well as the cloth that had been wrapped around Jesus’ head. The cloth was still lying in its place, separate from the linen. Finally the other disciple, who had reached the tomb first, also went inside. He saw and believed. (They still did not understand from Scripture that Jesus had to rise from the dead.)
