September's Very Best Beauty Products

Proving once again that he knows how to show a girl a good time, fashion icon Marc Jacobs has come out with a new, abundantly creative collection, Marc Jacobs Beauty. Just begging you to fool around: densely pigmented eyeshadows, moisture-drenched glosses and lipsticks, no-fade blushes, powder and gel foundations, liquid eyeliner and a mascara in blackest black. Oh, and 24 brilliant shades of high-shine nail polish. Let the fun begin!

Like fashion designer Michael Kors's gorgeous leather accessories, the six nail shades in his new makeup line ($18 each; Macys.com) are instant classics. Want to pair a great-looking bag with your manicure this fall? Here are three matchy-matchys made in heaven.

1. Sensation Nail Lacquer; Selma Stud Satchel, $348.
2. Envy Nail Lacquer; Selma Satchel, $358.
3. Hint Nail Lacquer; Selma Satchel, $358. (MichaelKors.com)

Kérastase Forme Fatale Voluptuous Blow Dry Gel ($35; Kerastase-USA.com)

Why we love it: Like most gels, this formula offers texture and hold. Unlike most gels, it smells of peach, rose, and peony, and doesn't leave hair sticky. Comb a pea-size amount from roots to ends before a blowout to create volume and keep flyaways at bay.

Boots No7 Perfect Light Loose Powder in Translucent

"I'm a sucker for anything that makes my face look poreless, which is why I love this powder ($12; Target.com)—so finely milled it's imperceptible on the skin, yet covers flaws superbly." — Val Monroe, O beauty director

"I collect hand creams the way some people collect fine wine. My current infatuation is a British import: Figs & Rouge Hand Cream in Cherry Blossom, Coco Rose and Mocha Orange, all infused with cocoa butter and organic essential oils. The creams are rich but not greasy and—best of all—are quickly absorbed."
— Val Monroe

"It really is a lot easier to apply makeup with the right brush. More fun, too, when your tools are as pretty as the new Sonia Kashuk Fall Brush Up 10-Piece Brush Set ($27; Target.com). The collection includes everything from the common (blush brush) to the curious (angled crease brush for eyeshadow). With glossy black-and-gold handles and rich magenta bristles, these tools are too good-looking to hide in a drawer; in fact, set on my bathroom counter, they remind me of a fall bouquet." — Val Monroe
