After a long day it's tempting to throw on a ratty old T-shirt when you hit the hay. We're guilty of reaching for our sorority shirts when it's bedtime , which is ironic, given that we spend an inordinate amount of time considering what to wear to work each day.

But the best way to unwind after a busy day might be to indulge in beautiful sleepwear . We're not suggesting you whip out a silk robe and fluffy kitten heels (though if that's your style, do it!), but putting a little effort into choosing the best pajamas might make going to bed just a little more enjoyable.

Here, five alternatives to those worn-out old marathon T-shirts.

1. A pajama shirt. This style has been given a new life, thanks to celebrities and designers who are treating the top as a blouse suitable for everyday wear. A soft cotton top is cozy for bed, but also works tucked into a pair of boyfriend jeans for your morning coffee run.

2. A pajama short set. This is sleepwear that we wouldn't be embarrassed to answer the door in (well, maybe). Comfortable and color-coordinated, what could be better than that?

3. A pajama pant set. This is really more our style. This screams "wear me and lounge on the couch for hours at a time!"

4. A chemise. This might be more sexy than comfortable, but hey, we like to cover our bases.

5. The onesie. Well, this takes the thought out of choosing a pajama top and bottom. We love options that are cute and easy to wear.
