Red and Green Plaid Regent Fit No sign of wear. Our non-iron dress shirt is crafted from crafted stretch twill from American-grown Supima® cotton and elastane. Finished with the established Ainsley collar that measures 4" from point to point. It is specially treated to resist wrinkles, and our signature 6-Pleat Shirring® at the double-button barrel cuffs and pucker-free seams reinforce Brooks Brothers' dedication to a well-made dress shirt. The Regent fit is a modern trim fit with chest and sleeves cut slimmer to the body.
