Ordered two sizes for my husband and missed the return window. The iconic, classic Scottish plaid that has graced holiday traditions for decades, Imperial Tartan is a celebration of the vibrant hues of the season: scarlet, navy, green and snowy white. This classic pajama set is accented with navy piping and finished with pearl buttons. This pajama is a lightweight, very soft flannel. The fabric is made from 100% of the finest quality cotton. It is yarn-dyed to prevent fade and brushed for added softness making the sleepwear feel absolutely luxurious, getting cozier after each wash.
