The only overalls on Wall Street are on hipster 20-somethings walking around the stock exchange.

According to TheStreet's Jim Cramer, the Wall Street suits have failed to grasp why people love the Cintas Corp. (CTAS)  brand. The corporate uniform company is known for its mass appeal to Middle America.

"People on Wall Street do not wear overalls. They don't know the power of Cintas," Cramer said at TheStreet's Financial Success Strategies teach in on Oct. 28.

Cincinnati-based Cintas has had a banner year so far on an improving industrial economy in the United States. In the three months ended Aug. 31, Cintas reported earnings of $1.48 a share, easily topping FactSet analyst expectations of $1.30 a share. During the same period, Cintas posted sales of $1.61 billion compared to Wall Street estimates for $1.57 billion.

Shares have gained about 30% since January. 

To be sure, nothing says positive employment trends like ordering more uniforms for workers.

Cintas derives about 77% of its sales from uniform rentals, which means it can often be a useful tool for digesting employment trends in the U.S. Cintas, Cramer said, is his "favorite way to play" the "industrial renaissance."

"I think it's a fantastic way to be able to play the employment numbers, which have been pretty good," Cramer noted.

Cintas' power and appeal comes from aligned interests between both management and investors, Cramer has said. But an impressive growth outlook in part stems from Cintas' 2016 acquisition of its chief rival, G&K Services.

"Cintas bought its number one rival, G&K, for $2.2 billion, and the stock hasn't looked back," Cramer said. "It's up 33% this year. It's not done."

The G&K deal will likely offer a significant amount of synergies over time. It's unlikely Wall Street has fully appreciated the deal's potential. 

For Wall Street to really get a gauge on the health of the economy, they might need to look a little closer at the overalls-producing kind of firms like Cintas. Added Cramer, "Cintas has been repeatedly underestimated."
