The key to this trend is making sure your pajama pieces look purposeful, rather than having an unplanned, just-rolled-out-of-bed vibe. If you're ready to really commit, I personally love a matching print set, whether in traditional stripes or a top and bottom in an exotic floral. Just make sure you style your PJs with a sophisticated shoe, like a white patent leather pump or a pointy-toe heel. Elegant accessories are a must too, so be sure to add a killer bag (perhaps a chic messenger or a studded mini bag?) and either a sleek bangle or a stack of skinny bracelets. If a head-to-toe pajama ensemble is a touch too much for you, you can still try this trend by simply wearing a nightshirt. I love a silky style, especially one with contrasting piping or polka dots. As for what to wear it with, stick to the classics: a black pencil skirt is always an excellent option (make sure to tuck in your top), or a cool pair of trousers would work too. However you wear your pajamas, the end result is sure to look chic and feel comfortable, which is why I think this is one spring trend you don't want to sleep on!
