Best Of: Now that Fashion Month is actually and officially over (too many forgot about Giles yesterday), the best of the month’s fashion’s been rounded up for your viewing pleasure and consequent envy. {Style}

Watch Out: Just in case you were trying to ignore her, two days after Becka Diamond was named NylonTV’s newest host, the actress is Who What Wear’s Girl of the Month - a coveted title that means she’s not going anywhere. {WWW}

Real or Rubbish: There’ve been a few whispers suggesting that once Condé Nast finishes their 25% cuts, they’ll bring Elle on board from Hachette. In that case, does Condé own every mainstream fashion magazine? And imagine a holiday party at which Katie Grand, Anna Wintour and Joe Zee all answer to the same boss. {FWD}

Back in the spring we talked about the news that Scientology’s most famous spouse, Katie Holmes was working on a children’s clothing line. And as far back as last fall, when Katie sported that jumpsuit creation, we pondered what sort of design project she was working on exactly.

Today we get confirmation from WWD that both the kiddo clothes and their grown-up counterparts will debut this fall exclusively at Maxfield in Los Angeles. The line - Holmes & Yang - is, as expected, designed by Katie and her stylist Jeanne Yang. No photos have leaked yet but it is “said to be full of classic fare.” I’m not really sure how to take that, especially if that jumpsuit was any indication of design direction.

I’ve never understood why people change the way they dress when they’re in a relationship.

After all, you had a personal style when you met said person making him/her well aware of what your usual garb looks like. And guess what? This person found you attractive enough to want to date! So why the major transformations? I’m just not feeling it.

But apparently some people are. Take Kate Hudson, who morphs her style depending on who’s arm she’s on, or girl-next-door Katie Holmes going all Kate Cruise glam-bot. And, of course, don’t forget the boho brunette, John Mayer-dating version of Jessica Simpson.

I guess I just think style should evolve more organically, not based on some other person who may or may not be around in a few months.

Does your choice of clothing change when you’re no longer flying solo? Or should you stay true to your style no matter what your relationship status may be?

Quietly, the news that Katie Holmes has been working on a line of children’s clothing has been floating around without any real confirmation until ELLE’s Twitter yesterday afternoon.

It seems the former Joey Potter’s foray into fashion as the face of Miu Miu for Spring 09 wasn’t even the beginning, since Katie’s reportedly been working on the line with her stylist, Jeanne Yang (whom you might remember let Katie design that white jumpsuit with her), for over a year.

Whether this is really because she couldn’t find cute/comfortable clothes for the most famous daughter ever, or because she’s jumping on the highly profitable designer kids wear market is unknown, and will probably stay that way.

Meanwhile, if Suri ends up the face of TomKittens Holiday 09, we’ll officially boycott any photos of her immediately.

“Tom and Katie just walked right up to the front, and we were like, Who the f*ck are they? They’re not even in fashion!” - Kate Moss, on having to wait to get inside last year’s Met Ball, in Vogue UK.

When we posted the first images of Blake Lively’s February Vogue cover, the discussion took a quick turn from does she or doesn’t she look amazing to who’s landed April’s cover.

Thanks to a few readers and some sneaky emails / texts, we think we have the answer. But since it isn’t nearly as fun to just tell you, let’s play a game. The clues:

1. “If you think this one is bad get ready. Vogue is now turning into TV Guide, April’s cover is even less deserved.”

2. “A cheesy television actress who came from a teen show - with bad commercial movies.”

3. She’s a former WB star.

4. The actress is “shaplier” than Katie Holmes, (which makes her prime for April’s Shape Issue) but shares the same initials.

Think you know the answer? Click to find out ours:

The first image from Miu Miu’s Spring 09 campaign with Katie Holmes is out - thanks to Vogue UK - and ready for the tribunal.

While some might go the “feline” description route, we’re struck by how much she looks like Joey Potter giving Dawson a disapproving face (probably because he’s giving her shit for wearing a designer dress, but anyway).

Still to come are the rest of the images, featuring the gaggle of models hired to flank Mrs. Cruise, including Imogen Morris Clarke, Katie Fogarty, Darya Kurovska, Myf Shepherd, Sophie Srej, Tilda Lindstam, and Elena Lomkova.

Scarlett Johansson’s rumored to be the new face of Dolce & Gabbana.

She’ll front their Spring 09 campaign, already shot by Mert and Marcus according to Style.com, though for beauty or fashion, no one knows.

Scarlett’s experienced either way. She’s posed for L’Oreal and Louis Vuitton, both of which should prepare her for Stefano and Domenico in case her numerous red carpet Dolce wearing moments weren’t enough.

Tthis puts the celeb count at three this spring with Katie Holmes for Miu Miu and Madonna for Louis Vuitton. The group model shots are at a bajillion and we wonder how either strategy is recession friendly.

Meanwhile, we’re secretly hoping Scarlett makes a cameo on Model.Live, since Cato Van Ee is in D&G’s Spring campaign, too.

She can address the major differences between acting and modeling and tell us how she strikes such a delicate Dolce/Stella balance.

A glimpse from your weekend:

You’re probably going to curl up in bed, post-holiday shopping, with the issue of T: Style that’ll come with your New York Times.

Why?

Because the issue will feature a double cover with Katie Holmes and Tom Cruise (you know you’ll read that interview over hot chocolate), and an in-depth piece on the many homes and lifestyle reinventions of Karl Lagerfeld (preview after the jump), written by Cathy Horyn.

So be super fashionable and look ahead.

Fashionologie’s reporting a rumor that’s getting backed up everywhere we turn:

Katie Holmes may be the Spring 09 face of Miu Miu, upsetting previous rumors of an all-model cast for the always-anticipated campaign.

The rumor purports that Katie will be surrounded by other models, who will undoubtedly be paid about a quarter of Mrs. Cruise’s salary, maybe even combined.

But honestly, this is so bazaar (when we think of Katie we still think of American Eagle) it might be ones of those things we don’t believe until we see. Stay tuned.

Vogue UK stumbled on a very fun(ny) fact recently:

That Tom Cruise and Katie Holmes approached Richard Prince about “a project” they’re working on, and were rejected because Prince said there was “no connection” for him.

So of course, the big question is, what is this project, and could it be a fashion collaboration with the artist a la Louis Vuitton? After all, Katie’s been seen out and about sporting outfits she co-designed with her stylist, Jeanne Yang, (at left) so her designer dreams are already evident, thought it would be curious timing since some people are already calling the time of death for celebrity clothing lines, Heidiwood having died quietly last week. (Though, yes, Katie Holmes and Heidi Montag are two very different types of celebrities, who obviously design two very different types of clothing.)

Or maybe Katie and husband are just trying to commission an artist who happens to be very tied to the fashion world?

Let the guessing game begin.

“Duvets (the Czech supermodel Karolina Kurkova) and tartan crinolines (Sarah Jessica Parker) have previously been requisitioned hot off the catwalks, giving bloggers endless pleasure as they earnestly debated the unfolding catastrophes. This year the actress and singer Charlotte Gainsbourg came as a lung, Kate Moss as a barmaid and Katie Holmes - Mrs Tom Cruise - finally outed herself as a Thetan.” —The London Times on the Met Ball.

Marie Claire UK reports that Posh Spice is in talks with Fox to host her own reality fashion show.

The name? Fashion Nightmares.

We’re torn.

We think Posh would make a totally entertaining and adorable host - we could just picture her quoting That Extra Half an Inch every time she comes across a soccer mom in slouchy sweats.

But we’re not so into the idea of her telling women why trouser jeans will improve their lives (a la Clinton and Stacey,) and seeing her teeter through “beauty pageants and backwater towns” in tiny Roland Mouret dresses and ginormous DVB shades acting like an alien from Fashionista Land trying to convert the bourgeoisie.

In short, we’re not sure we’re ready to see Posh make other girls cry.

But of course, we’ll watch no matter what.

As a sneak preview, check out Victoria tonight on Project Runway as a Guest Judge. We can’t wait to see Christian freak out about her fierceness.

Alison asked this morning if Katie Holmes wanted to look more like Christina Ricci.

After all, her new and very severe haircut is so very goth, it adds a good 10 years to the well-married movie star.

We think it’s more of a nod to Anna Wintour, but there is a small goth connection:

Katie’s arched eyes and deep, shiny hair looks an awful lot like our favorite tantrum teen, Emily the Strange.

With her glowering appeal and her “don’t-touch-me” stance, Emily’s entire being seems to be Katie’s subtle subtext - unless you’ve actually started to believe she’s totally in love with her life, in which case, well, it’s just a very chic haircut.

Whether or not a person has killer style is truly up to debate. We can’t remember how many arguments we’ve had over whether Rachel Zoe always looks amazing or just 70’s.

But whether or not someone actually has style- as in, a manner of dressing which is so recognizable it can be copied or even repackaged and sold on TopShop- is not really up to debate at all.

The newest US Weekly has chosen a curious pair to headline its “20 Best Makeovers” issue. It heralds Katie Holmes as “Most Improved” and Carrie Underwood as rocking the “Sexiest New Style.”

Now, we’re not saying that we expect US Weekly to cover anything other than celebrities looking either stunning or like train wrecks, but this line up of celebrities with enviable “style” just doesn’t make sense.

We can’t imagine anyone ever saying, “God, that dress is so Katie!” We’re not even going to bother retyping that with Carrie’s name, too.

At least US Weekly has given us a whole new style debate to dive right into: does it really count as style if you have a professional laying your outfits out for you?
