While I love throwing on a pair of heels and dressing up, there is virtually nothing better than being able to leave your house wearing whatever it is that you just slept in.

To be fair, sometimes I do. My current sleepwear situation includes an old college sweatshirt and a pair of flannel shorts, which occasionally does double-duty for me as dog-walking gear. I've worn that uniform grocery shopping, to Starbucks or to mope around my apartment when I'm sick.

Lucky for me, pajama dressing has transitioned from just "wear alone in your apartment" to acceptable outside attire. Innerwear as outerwear? Say it ain't so!

I'm not talking about my tired old hoodie and my flannel shorts, however. Silk shirt-pant combos, wide-leg pants and contrast trim are all fair game for both naptime and brunch.

Here's how to wear the trend:

For the first outfit, pair a breezy long-sleeve pajama top with a graphic leather skirt and high heels. The skirt will lend an edge to the prim top, and the heels tie it all together.

Next, pair a contrast-trim matching set with a colorful heel to add some much-needed brightness to the look.

Finally, a pajama top in a cheery print will do wonders when paired with denim culottes and a basic ankle boot.
