It was tough, but Robinson, who campaigned for Bush's father in 1988, threw himself into it.
Six days later, he mailed the shirt to the White House.
"It was an honor and a pleasure," Robinson said. "They told me they would try to get a picture of him receiving the gift or wearing it."
White House representatives were unable to confirm Friday that officials had ordered the shirt from Toes on the Nose. The company's president, Richard Allred, said he thought he was being had when he got a call asking for a presidential shirt.
"To tell you the truth, I'm not sure how they found out about us," he said. "But it was definitely a big surprise for us. I was like, you've got to be kidding me. I thought one of my friends was messing with us."
The design that Robinson created featured a number of famous Bush-related symbols: the Presidential Seal, the Yale logo, Camp David and Air Force One, along with the initials "G.W.B." on the right sleeve and "President Bush" written below the Toes on the Nose label.
Allred said the company mailed the shirt earlier this week in hopes of making the Friday birthday deadline.
"I'm 99.9% sure that he got it today," he said.
