Just when you thought you’d seen every Muse under the sun, they come out with another one. Behold this Yves Saint Laurent Muse Two-Flap Shoulder Bag for fall, done up in light gray lizard-embossed suede with a darker gray flap and sides. The lizard effect is cool, and I’m dying to touch one of these babies, but when all is said and done I’d probably prefer a solid color. You? Available at Bergdorf Goodman for $1,795.

Perfection. I absolutely love this chic and summery ensemble that Lauren Conrad has put together - the diva shades, the slouchy white tee, the navy skirt, the gorgeous honey brown strappy sandals, and the matching Marc by Marc Jacobs handbag. I’d wear it all as is - minus LC, of course. Her clothing line may be a bit hit or miss, but there’s no denying that the girl knows how to dress.

Why try to fight the current Alexander Wang mania? The designer’s purses are selling like hotcakes, and every starlet on the block seems to have one swinging from her arm. And here’s the latest handbag to drool over: the Trudy Tote. This roomy gray leather tote features perforated sides that fold into the bag, plus decorative silver rings for a little extra somethin’-somethin’. It’s a terrific everyday tote for you downtown girls…provided you can get one before it sells out. Available at La Garconne for $825.

Love her or hate her, you can’t deny that Sienna Miller always makes interesting fashion choices. Here the starlet is hitting Australia’s Bondi Beach with a pal, wearing white jazz shoes (hmmm), dark-rinse acid-y jeans (hmmm), and a gray Yves Saint Laurent Besace Messenger (okay, I love it). The handbag’s stripey croc pattern is eye-catching, and I love its casual slouchiness tempered with a luxury quality.

“Gigli” aside, is it wrong that I’m secretly thrilled for a new Jennifer Lopez movie? I even liked “Monster in Law.” So I’m delighted to see La Lopez out and about on the set of her new film, “The Back Up Plan.” And the star didn’t disappoint style-wise, looking every inch the diva in her giant shades, white embellished top, and Adriana Castro Python Meissa Hobo. I love the neutral snakeskin print, and it looks fabulous with her outfit. The purse also comes in a selection of bold hues, if natural isn’t your thing.

Blake Lively of “Gossip Girl” shouldn’t have any trouble hailing a yellow cab. 1) She’s famous. 2) She’s gorgeous. 3) She’s accompanied by a beautiful black Chanel purse…and who wouldn’t want that in their backseat. I love this city-chic look…nicely fitted jeans, a fab handbag, and a pretty blouse is all a gal really needs. Oh…and a ride.

Jessica Alba chilling in Malibu with stylist Rachel Zoe? Now that’s bananas. The pretty mama looked very glamorous and summery in her flowing black caftan and straw fedora (so chic), and though I love her black Chanel 2.55 purse, it’s not something most people would take to the beach. I’d be petrified that I’d get sand or salt water on it, but maybe that’s just me. Rachel, meanwhile, looked skinny in a long dress…nothing new there.

Talk about putting on the glitz. There was a lot of glamour at the Armani Prive fall ‘09 couture show in Paris, and not just because Megan Fox and Cate Blanchett were sitting in the front row. The collection, heavy on sleek blacks, steely grays, and a lovely cobalt blue, was accessorized with beaded caps, giant statement necklaces, and, of course, handbags. About those purses…think extravagant and lavish, with lots of metallics, gem and sequin details, ornate chains, animal prints, and a funky blue paillette creation. They’re not the most subtle bags, but for the right ballgown…why not?

Huh. I know she’s wearing bunny ears and an anaconda-esque Alexander McQueen knit outfit that wouldn’t look out of place on the set of “Star Wars,” but considering some of her other get-ups, Lady Gaga looks almost demure here. (Is it wrong that I want those ears?) The singer accessorized with a sleek black and white striped clutch, but I can’t place the designer. Can you?

Sheesh - how chic can one woman look in nothing but black leggings and a gray striped top? The gorgeous Uma Thurman managed to look elegant with little fuss in Paris, and a lot of the credit goes to her amazing black cross-body handbag. I love the woven flap and ribbon detail - stylish, but versatile enough to work with a low-key ensemble like this one. Put your designer guesses in the comments section!
