I won't lie -- as a work-at-home mom, there are at least a couple days a week where I resort to a uniform of yoga pants and a hoodie. I'm not leaving the house, so there's really no sense in wasting a perfectly good outfit if no one's going to see it.

But even if I do manage to squeeze in an exciting trip to the grocery store on one of my yoga pants days -- I don't bother to change, because yoga pants are fairly well accepted as an appropriate wear-anywhere outfit in today's society.

However, there's one piece of clothing in particular I will never be caught dead wearing in public -- and that's pajamas. Sleepwear is called sleepwear for a reason, people -- and it needs to stay in the bedroom where it belongs.

Ok, so I know celebrities can usually get away with wearing some pretty wacky style trends simply because they're famous, but please, please, please -- someone tell me celebs stepping out wearing pajamas isn't a fashion statement that's going to stick! I know there's the whole comfort factor and it can be so tempting to just roll out of bed & leave the house without bothering to change -- but I just can't help but see running around in pajamas as borderline lazy. (Unless you're quickly dropping the kids off at school & coming right back home. That's different.)

Victoria's Secret model Miranda Kerr looks amazing in anything, but even she had a bit of the mom frump going on when she wore her pj's to catch a flight at the airport.

Celebrities are often envied for their extravagant wardrobes, as most of us would love to have an unlimited bank account to go on a fashion shopping spree anytime we want. They definitely go to extremes to impress and turn heads on the red carpet, but have you ever wondered what they look like when they roll out of bed in the morning? Because chances are they look a lot less perfect when a hair & makeup team hasn't gotten a hold of them yet. And aside from their appearance upon rising, it's also interesting to think about what kind of sleepwear they prefer to wear in the sack each night.

Victoria Beckham is no stranger to the world of fashion, so you'd think she'd pick out the priciest silk pajamas she could find to get her zzz's at night after the kids are in bed. But she actually keeps things pretty cheap when it comes to her overnight attire.

Lately, Scarlett Johansson isn't really topping my favorite actress list. Maybe it's the way she handled that nude photo "scandal" or that awkward "retro" hairstyle she rocked for the premiere of her new movie, We Bought a Zoo. OR perhaps it's her most recent comments on sweatpants that really take the cake in the annoying department.

Johansson told Style.com that she's not the kind of person who "just slops around in sweatpants." You know what? I take offense to that. I wear sweatpants all the time, and I don't think it makes me a "slop."

I understand where she's going with the comment. She likes to feel put together. I can respect that. But woman, COME ON. Save yourself some sanity! ScarJo has no idea what she's missing out on.

Just because you're wearing sweats doesn't mean you have to look like you've put zero effort into your ensemble.

The best part about Christmas morning is the cinnamon buns. That is a fact. The second best part about Christmas morning is staying in your pajamas 'til noon and wearing gift bows in your hair. Goodness I love eating breakfast pastries in PJs with paper and string on my head, don't you? I was thinking that this year I'd look extra good doing it, though. Instead of an old high school basketball tournament t-shirt and stained sweatpants, I think I'm going to step up my sartorial game and actually wear some nice pajamas. Not, like, silk ones or whatever -- I'm not some sort of gigolo -- but cute, holiday-appropriate ones. I've never had a pair of cool PJs, so really, there's no better time than now to hop on the super-duper sleepwear train. Here are five pair of Christmas morning pajamas I'm considering:

I don't know what sort of bedtime trauma I endured as a kid, but there's something about pajamas that I can't stand. Well, it's more that seeing people in their pajamas is what I have a problem with. It just makes them look so vulnerable! And a little bit insane. Because anyone who wears PJs outside of the privacy of their own bedroom has got to be a smidge unhinged. I know I might be alone on this point, but when I saw the photos of Rihanna greeting her fans in her pajamas, I cringed. She's lost it, no?

Rihanna's style has taken a left turn recently and this PJ fiasco perfectly shows that she's kinda lost that fashion feeling. And maybe a little bit more.

Natori announced today that it will partner with Target to offer sleepwear in the $9.99 to $34.99 price range.

The sleepwear will be available in October.

I'm pretty excited about this news -- my favorite pieces by far from the Calypso St. Barth for Target collaboration were the chemises. Now that it's hot outside, I've been wearing them just about every night.

It only makes sense the sleepwear could be a design collaboration success -- you can get away with cheaper, flimsier fabric and still end up with cute, comfortable sleepwear. It's harder to do that with regular clothing.

Want to see more of my favorites from Natori? They should give you at least a loose idea of what to expect at Target this fall.

I had to buy some Hello Kitty pjs. For a party. It was a pajama party, and Kiddo wanted me to go in Hello Kitty pjs too, just like her. What can I say? I caved. I bought some, going against every fiber of my style-being as I am a firm believer that cartoon-wear, you know, those character t-shirts, a) belong only on kids 18 and under, and b) if they must be worn by adults, only within the confines of the respective theme park. It screams you're just wanting someone to come up and ask you about your trip to Disney World ... or that you haven't done laundry in three weeks and it's the only clean shirt you have.

But, while looking around for some Hello Kitty pjs, I had a change of heart. I was wrong. Yup, I'm admitting it. I found some amazingly cool cartoon shirts (and yes, a pair of Hello Kitty pjs) no one would be embarrassed to wear.
