Can’t get enough of Mariah Carey’s addicting rendition of “All I Want For Christmas Is You”? Fear not, there’s always the Mariah Carey-designed Nativity Set (pictured above). Yep, this is real. It’s also available for purchase on HSN alongside several other Mariah-themed holiday decorations.

And while I was initially skeptical about the prospect of decking the halls with anything Mariah Carey has designed (come on, she’s the poster girl for ‘Glitter’ and rainbow airbrushing)—at the end of the day, her ‘All I want For Christmas Is You,’ video has over 31 million YouTube views. So she might as well be Mrs. Clause.

And without further adieu, THE video:

While the pint-size star of the Jersey Shore already has a line of sunglasses, sandals, and slippers, Nicole “Snooki” Polizzi is breaking out the big guns for her very first perfume line, which hits HSN.com today. While the final product smells like kiwi (i.e. “flirty and bubbly, you know, like my personality, and obviously something DTF,” she told Jay Leno on the Tonight Show), Ms. Polizzi claims she did initially experiment with notes of pickle.

The perfume—which comes with a matching leopard tote bag—retails for $45 here on HSN.com. The reality star has been tweeting up a storm about today’s product launch, which will include her very own TV segment, “A Very Snooki Holiday Gift Special” airing on HSN at 8 p.m. EST.

Mark Badgley and James Mischka, and one of their Fall 2011 HSN designs

Last week, we went to HSN’s Accessories Preview, and caught up with designers Mark Badgley and James Mischka, Brittny and Lisa Gastineau, and Ahmed Akkad (who all design jewelry lines for HSN) to talk about what’s big in jewelry for fall. And the resounding consensus? Art Deco.  And we couldn’t be more thrilled that the geometric costume jewelry craze from the ’20s and ’30s is back with a vengeance.  Check out what some of our favorite designers had to say about the trend:

Mark Badgley, who co-designs the “American Glamour Badgley Mischka” collection for HSN with James Mischka, says they always look back to costume jewelry when coming up with their HSN designs: “We always do a line of vintage-inspired jewelry for [HSN], this is from our Art Deco group,” he says of the crystal cuff above. And luckily for us, he says that same inspiration is derived from the brand’s Badgley Mischka couture line. “It’s James and I and the same design team who design both our couture collection, as well as the HSN line, so the aesthetic is very consistent.”

Lisa Gastineau, who designs “Gastineau Glamour” collection with her daughter Brittny, tells us the Art deco decade influences her designs as well: “We definitely use the celestial aspect of Art Deco in our designs. We often use the star as the core of many of our pieces,” she says.

Ahmed Akkad, whose eponymous line is deeply rooted in Art Deco influence, says the era factored prominently in setting the tone for future designs. “[Art Deco] is the beginning of modernism; it’s the beginning of the time for women when jewelry changed from dainty little things to more confident and assertive jewelry. The scale there is impeccable,” he says. “If you look at 1960′s design–which is a very modern design–most of it has its roots in deco.

Although the pieces we previewed will all be available for Fall 2011, all three of the designers have used Art Deco in this season’s designs. Shop them all below or on HSN.com here now.

With Rachel Zoe and Janie Bryant both having lines for QVC, it’s safe to say that home shopping networks aren’t what they used to be. Which is why we got pretty excited when we heard about the HSN capsule collection with Lucky Magazine, which includes pieces from Thread by Thread Social, Linea Pelle, and Matt Bernson and is being sold at discounted prices for a limited time on HSN today from 1pm to 3pm and 10pm to 12am.

(If you miss the “event” today, don’t fret, you can shop the full-priced line HSN):

Linea Pelle

There’s no denying that the LP by Linea Pelle “Newport” Leather Satchel ($249.90 now, $219.90 at event) is the ultimate fall accessory. The rich caramel color, convertible straps, and the sheer size – need we say any more?

There’s something about studs and leather that is just so perfectly classic so this LP by Linea Pelle “Newport” Stud Leather Belt ($79.90) makes us oh-so-happy and oh-so-excited to snatch up more than one.

Cross-body bags are the best going out pieces and with a classic cut and color like this LP by Linea Pelle “Catalina” Leather Crossbody ($149.90), you can’t go wrong.

Thread by Thread Social

We love the way this Thread by Thread Social Long-Sleeve Sweater ($59.90 now, $49.90 at event) fits and the charmeuse bow makes it effortlessly chic. Wear it with skinny jeans for a night out with the girls.

The basic drop-waist and looser fit of this Thread by Thread Social Knit Dress with Dolman Sleeves ($59.90) makes it super comfy and easy to dress up with a pair of peep-toe pumps or down with a pair of boots.

Every girl needs an LBD and this Thread by Thread Social Ponte Dress ($79.90) is a perfect choice. Kick it up a notch with some sparkly bracelets and pumps.

Matt Bernson

If there’s one shoe that screams ‘fall,’ it’s this Matt Bernson Special Project “Bomber” Leather Boot ($199.90 now, $189.90 at event). We’d love to rock these this season with a faux fur vest.

The metallic cap toe and comfy leather of this Matt Bernson Special Project “Waverly” Leather Flat ($89.90 now, $59.90 at event) will make you want to buy it in several different colors.

A good boot transitions well from fall to winter and Matt Bernson Special Project “Tundra” Suede Motorcycle Boot ($199.90 now, $179.90 at event) is one of those boots. We absolutely love the soft fabric and edgy details.

This F+C Evy’s Leather Satchel by Anna Corinna ($300) is perfect for work and weekends.

A lot of big names land at HSN, and most of their stuff is pretty cute. You could wear this  IMAN Global Chic Shimmer & Shine All Over Sequin Top ($49.95) out at night, and pair it with these American Glamour Badgley Mischka Stretch Skinny Jeans ($59.90)

If you’re over the basic gladiator sandal, try a pair of Libby Edelman “Cindy” Rope Gladiator Sandals ($59.90).

While Paris Hilton doesn’t mind paying $65,000 for her sunglasses, we prefer to be a little more practical. It seems retro is coming back–and who better to take a fashion cue from than Twiggy – former ’60s model, (and more recently, America’s  Next Top Model judge).

These ’60s-style Twiggy London for HSN retro sunglasses ($24.90) fit the bill–their horn-rimmed details come in three different colors, but we prefer classic tortoise shell brown. They’re a lot less expensive than a pair of Ray-Bans, and ahead of the fashion curve.

Get 70% off sunglasses by Lanvin, Nina Ricci and Proenza Schouler at The Outnet, plus check out our guide to celebrity style sunglasses. You can’t go wrong with a new pair of jeans for spring, either: try Oprah’s favorite, CJ by Cookie Johnson jeans, or check out the best skinny jeans.

I was invited to see what happens behind the scenes at HSN’s headquarters in Florida today, and Stefani Greenfield, of Launch My Line and Scoop NYC fame is on today.

While HSN once had the stigma of being for little old ladies and insomniacs, these days, there’s now a hipper crowd inhabiting the brand. I met with the designers behind Badgley Mischka (seen below), whose newest project is American Glamour for HSN.

While they admitted they’re a bit nervous for their upcoming spot on HSN this Wednesday and Thursday, they didn’t mention that some of the items are actually available early, on HSN.com now–so get in on it before it sells out! Catch the duo on HSN Wednesday March 17 at 12pm for Jewelry Hour, and March 18 from 10-11pm, 3-5pm, 7-8pm and 10pm-12am.

How awesome is this gold chain bracelet ($129) that doubles as a watch?

This royal blue, sky blue and turqouise ombre scarf ($29.99) is perfect for adding pizazz to spring outfits.

This dome satchel ($329) is the kind of piece that will always remain classic. In HSN’s true form, you can pay it all at once, or in 3 payments of $109.

Get even more accessories in our guides to the best necklaces, and check out an American denim classic, skinny jeans and Oprah’s favorite, CJ by Cookie Johnson jeans.

Twiggy’s purple pumps (left) are a great way to add color to the neutral spring fashion trend, and these rich Franco Sarto Purple Pumps (right)($88.95) will have the same effect.

Twiggy’s croc embossed watches (left) in candy colors will get you ready for spring, and this AK Anne Klein Croc Embossed Watch ($55) will brighten up any outfit.

Twiggy’s offers a black handbag (left) for the practical girl, but we suggest trying the green option like this Latico Leathers Green Handbag ($159.00).

Check out another model-turned-designer Molly Sim’s jewelry collection for HSN, then see our guide to the best spring trends, or the best trench coats you can pair with these colorful accessories.

This braided necklace ($114.95) makes a big statement, and it will bring new life to any dress for day or night. Molly models this necklace (in gold) with her poppy-colored dress above.

These clip-on faceted stone earrings ($39.95) have a vintage, art deco feel. The clear stone and gold setting make the sophisticated earrings stand out.

This medallion drop necklace ($69.95) looks really unique: the chain on the necklace is delicate and simple, but the rhinestone medallion and gold tassel will still stand out–a great choice if you’re not into statement necklaces.

Check on Sims on HSN today at 12 pm, 1 pm, and 9 pm.  See more great accessories in our jewelry guide, or check out our guide to celebrity style for some closet inspiration.
