The nation’s largest men’s big and tall specialty retailer is partnering with a direct-to-consumer apparel brand known for its signature untucked shirts.

Starting yesterday, Destination XL Group Inc. (DXL) began offering an assortment of shirts from Untuckit in Big + Tall extended sizing. The collection consists of existing Untuckit shirts in new sizes and lengths never offered before.

Shirts at the Untuckit.com e-commerce site are currently available in sizes from small to XXXL, in up to five different fits. The collaboration with DXL will further extend this sizing range from 2XL to 4XL regular fit, 1XL to 4XL tall fit and 1XXL to 4XXL extra tall fit. The Untuckit, Fit By DXL shirts will be available only at DXL.com, with select stores offering styles to try on for fit.

“Our customers have asked and we listened. We’re excited to team up with DXL to fit even more guys who want the perfect untucked shirt,” said Untuckit Founder Chris Riccobono. “We think combining DXL’s perfected Big + Tall fits with Untuckit’s high-quality fabric and untucked length will hugely affect the Big + Tall space. We’re excited to finally answer the call from guys who love our shirts and have consistently asked us to make larger sizes.”
