Thanks to her longtime hairstylist, Oscar Blandi, she got the glamour of wearing her hair down without the stickiness of hair falling on the back of her neck in hot, hot, hot summer weather. INSIDER TRICK: To create balance, Blandi created a side part and gathered Ripa's hair into a ponytail on the opposite side of the head. "We were trying to create a very romantic look with her hair down, so I let let her soft waves fall over one shoulder," says Blandi.-Polly BlitzerCheck out In Style contributing editor Polly's Web site, beautyblitz.com

From colored lace to thicker brows -- try out a new set of fashion and beauty ideas for fall.

A dark part used to mean you missed a salon visit. But imperfection can be cool, provided roots are only a few shades away from your highlights.

2. Go Short for Black Tie
Yes, you can wear an LBD in a formal setting, but choose one with a beautiful detail such as a giant satin bow or a graceful tulip hem.

3. Stay in Sandals
No need to retire them yet. Strappy footwear looks great for fall with dark stockings (as do peep-toe pumps).

4. Grow Out Your Hair at 40
Buck the trend to trim your tresses. But condition so your locks are as lush. We like Pantene Pro-V Beautiful Lengths conditioner, $4; at drugstores.

5. Go Sleeveless
It's time to rethink the jacket for fall -- 3.1 Phillip Lim, Diane von Furstenberg and Calvin Klein all showed sleeveless ones as a bold new option.

Jennifer Aniston could be the poster girl for great jeans -- they seem to be her uniform of choice. Here she opts for a slim bootcut style from Degaine. "I started this style from our skinny jeans and opened the bottom slightly to make it more casual," says Gregory Abbou, designer for Degaine. "Jennifer is not a tall girl but she likes the bootcut look because it's very casual. Bootcut jeans can make you look shorter because the thighs and knees are too loose, so by using a skinnier base we are able to give the leg a better shape -- it makes you look taller and slimmer." The denim also helps make this jean ultra-flattering and wearable. "The fabric feels like a second skin," says Abbou. "It has enough stretch to hide the little imperfections so you can feel sexy without compromising comfort."

Alexis Bledel. Photo by John P. Iblis/JPI StudiosGET THE LOOK: It's impolite to call people names, but Hollywood is chock full of loud mouths. Stars like Alexis Bledel haven't uttered a controversial word, but they've made as bold a statement as any with creamy, nearly-neon fuchsia lipstick.
INSIDER TRICK: Get in line! With a shade this bright, precision is key. Carefully swipe on lip color with a stiff lip brush.
