Bloggers are always getting accused of sitting around the house in their pajamas spouting off opinions. I suppose this is because you can't take the opinions of someone wearing pajamas too seriously. What these folks don't realize is the glorious history of the pajama and the qualities which make it the ideal form of clothing for deep and penetrating thought.
When talking about pajamas I don't include pajama 'tops'. Those weird button-down pseudo jackets are a stylistic and historic aberration and aren't properly part of pajamas at all. They're something a marketing guy added on in the 1950s to raise the price of the pajamas for sales in department stores. A good cotton t-shirt does a way better job of topping your pajamas. Traditionally pajamas are just the comfy, cotton drawstring pants. The term originates long ago in India where pajamas or pyjamas were loose-fitting hemmed pants which tied at the waist. Because they were so comfortable this style of pant spread all over the east and was eventually brought back to England by the nabobs who returned from colonial service and brought their favorite pants with them. They caught on fast in America as well where people were getting awfully tired of the work and humiliation involved in wearing longjohns - pajamas broke the tyrrany of the butt-flap.
What made pajamas the international clothes sensation of the 19th century was their versatility and comfort. Pajamas were not designed or intended exclusively for sleep. They're multi-purpose, designed to wear all the time for work, sleep or lounging about munching melon and sucking on your houkah. Easy to put on, easy to take off. No need for a belt or suspeenders. The ultimate in practical legwear. Those qualities account for the recent pajama renaissance and their popularity among bloggers. It's easier to think great thoughts when you're not constricted by heavy fabrics, zippers, belts and the need to avoid wrinkling a fine fabric. Admittedly, some Victorians looked on pajamas as a bit decadent, but they couldn't resist the tide of change, and by the 1890s they were ubiquitous, favored by the intellectuals of the Roaring 90s, the perfect clothing for informal wear while reading Oscar Wilde. From there on, into the 20th and 21st centuries pajamas have been a fixture of the leisure wardrobe.
When you go out to buy some pajamas to blog in be aware that not all pajamas are created equal. While there are many fine pajamas out there, watch out for imposters of inferior quality and materials and keep in mind that price isn't always an accurate measure of quality. There are certain characteristics you want to be sure your pajamas have. They should be made of 100% cotton as they have been down the ages. Cotton breathes, it doesn't mind being wrinkled, and it's soft and skin-friendly. They need a good, loose fit in the leg so you can sit in the lotus position in front of your monitor. A drawstring is a must, but the modern innovation of an elastic waist is a big plus. Another very desirable feature is pockets. You need someplace to keep the remote control, some snacks and a copy of Chariman Mao's Little Red Book.
