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 trousers. Comfort and accessibility define the Gap style and the use of colour has become something of a signature for the label. The nightwear range from Gap includes comfortable Sherpa lined hooded dressing gowns, brushed cotton night shirts and plaid flannel trousers. There are double knit polka dot dressing gowns, 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 trousers, and chambray night shirts in a range of colours.
