I finally replaced my old cotton pajamas with a silk set, and the difference in feel is noticeable. The lapel collar looks classic, while the fabric has a soft sheen that makes the whole outfit feel more refined. I like that the fit is relaxed enough for lounging without looking baggy. My wife even commented that I looked unusually well dressed for someone sitting on the couch watching TV, haha. The silk does need a little extra care, but I'm happy to make the effort. Sometimes the small upgrades are the ones you appreciate most.
