The clean cut, American optimist aesthetic of the Gap brand has gone a long way to helping it achieve worldwide success in everything from knitwear to pants. Comfort and accessibility define the Gap style and the use of color has become something of a signature for the label. The nightwear range from Gap includes comfortable Sherpa lined hooded robes, brushed cotton night shirts and plaid flannel pants. There are double knit polka-dot robes, brushed cotton nighties and printed poplin sleep sets, as well as lace trimmed camis. The line also include tie-up capris, poplin night shirts and nighties, as well as jersey pants, and chambray night shirts in a range of colors.
