The word pajama is derived from the Hindi word 'pajama' which means 'legwear'. British colonists brought pajamas to Europe in the mid-17th century. In the 20th century, fashion spread all over the world. The pajama models worn by men, in particular, used to be domestic clothing made of light fabric and used when sleeping. However, today men's pajama sets are produced in two pieces. Pajamas in the form of belted jackets, shirt-type, short-sleeved t-shirts or long-sleeved t-shirts combine with comfortable pajama bottoms, promising a very comfortable sleep for those who wear them. Men's pajama sets with elastic and light fabric that grasp the waist without a button have been the choice of gentlemen who are fond of their comfort.
