A few years ago my friend’s kids, who were perpetually late for school, suggested to their mom that they sleep in their clothes soas to save time getting ready in the morning. The experiment lasted a few days, until presumably the kids and the mom ran out of clothes that could take them from nighttime to daytime. Not many PJ’s double as ready-to-wear and vice versa. Well, until now. The silky sets are everywhere for Spring and while they are lauded as a must-have trend item, I think the real appeal is in the convenience. In other words, feel free to hit snooze.
