But the owner tells us they're not making a profit.
72 shirts were given away at Thursday night's candlelight vigil held at Magic Island. Because of the high demand, they made 250 more of the shirts Friday.
They'll be sold for $5 at Buti Groove on Kapiolani Boulevard. Owner BJ Sabate says they came up with the design is just a half-hour.
He also tells us some have said they're just taking advantage of a tragic situation to make quick buck. But he says they're actually taking a loss from making the shirts.
"I don't really take it personally you know, I'm a big fan and what I was doing was just in my business, in my line of work, is what we do, is T-shirts," he said.
