Whether it's Jessica Biel's butt, Jessica Simpson's chest, or Jessica Alba's abs, Hollywood certainly has plenty of parts to envy (and plenty of Jessicas!). We compiled a list of Hollywood's best arms, abs, and everything else, along with tips from celebrity stylist Lindsay Albanese on how to make yours just as sexy.

The dresses may look picture-perfect, but Oscar night almost always comes with some last-minute scrambling behind the scenes. With the 2010 Oscars nearly upon us, we asked some of Hollywood's top stylists to spill their favorite "oops" moments from the Oscars and other high-profile events of the past:

Zip It Good
"One of the biggest stylist's nightmares is that a zipper will break or get stuck. With one actress, the zipper of a purple ruffled Dior gown wouldn't budge as we were about to step out on red carpet. I ran to my car, got a pair of Dr. Rey Shapewear, which is like Spanx times 100, and some Zipper Ease, a zipper lubricant, and got the zipper up. She got to the red carpet and no one knew." -- Anya Sarre

Red, Red, Wine
"At one event, Anne Hathaway was wearing a white Valentino strapless silk knee-length dress and someone spilled a glass of red wine down the front. She was completely unruffled by the whole thing." -- Jamee Gidwitz

All Choked Up
"Several years ago, I was dealing with a very large, well-known actress who was up for a nomination. The necklace she wanted to wear didn't fit her neck. You can't send these things back two days before and say 'give me an extra four inches.' Fortunately, she wore hair longer in back, so I took the chain and threaded it through various strands on either side of the necklace, creating an extender that would allow her to wear it." -- Michael O'Connor

Dress Drought
"Years ago, I was dressing Selma Hayek for her first time at the Oscars. Back then, few designers (mainly just Giorgio Armani, Versace and Bob Mackie) were dressing Hollywood. Giorgio Armani invited Selma to fly Paris for his show, and she found out the day we were leaving that she was presenting at the Oscars. She's very loyal and wanted to wear Armani, but was concerned about the fact that there weren't a lot of Armani gowns to choose from. Luckily, we found a beautiful nude sequin tank gown that was pretty elegant and Selma really liked it. We added a real vintage tiara and heavy blue eyeshadow -- it looked elegant and chic." -- Phillip Bloch

Heads Up
"I lent a platinum and diamond hair clip to an actress to wear. She was concerned that wearing something in her hair wouldn't be as secure as a pin on her dress. I told her not to worry and used hair spray and combs to affix the piece, which was heavy. As she came through with the press following her, she turned her head to look at me and the piece gave way and went flying into the air. Someone else grabbed it!" -- Michael O'Connor

Heel the World
"I dressed a presenter at the Oscars and as soon as she stepped on stage to present, the heel broke on her Jimmy Choos. She faked it on the ball of her foot, read the names and laughed where appropriate, presented the award, hugged the recipient and walked off stage. She really pulled it off and no one knew." -- Jamee Gidwitz

p.s. Check out our Oscars predictions to see what this year's top nominees and celebs might be wearing.

Hollywood's biggest night is fast approaching, and we've got some Oscars predictions of a different kind. Six top celebrity stylists -- Anya Sarre, Michael O'Connor, Jessica Paster, Lindsay Albanese, Phillip Bloch and Jamee Gidwitz -- give us their take on what acting's elite should wear to the Oscars.

The Client: Sandra Bullock (Best Actress nominee for "The Blind Side"

Anya Sarre: "I'd love to see her in a vibrant color or white. White is a huge trend in award shows this season and she hasn't worn it yet. It stands out in a sea of black and looks great with gold accessories--like a gold statue! I might put her in Angel Sanchez (he did her wedding gown). Or Alexander McQueen, which she got great feedback from after the SAG Awards."

Jessica Paster: "I've dressed her for the Academy Awards (in a winter white dress with feathers at the bottom from Oscar de la Renta). I'd love to see her in something feminine and girly. Oscar again, Zac Posen, Christian Dior, or Jason Wu could be beautiful."

Lindsay Albanese: "She wore dark, bold colors to the last two award shows so I'd love to see her in something softer. Maybe a one-shoulder or Grecian-inspired romantic dress from Marchesa or Versace. She's very small and petite--pretty much a stylist's dream to dress. "

Jamee Gidwitz: "She'd look great in chiffons or something flowy. I'd choose something from Collette Dinnigan, Alberta Ferretti, or Vera Wang. She should wear something that evokes her inner personality, a more feminine, silhouette, maybe in lavender or silver.


The Client: Helen Mirren (Best Actress Nominee for "The Last Station")

Sarre: "I would love to see her in something navy, with classic, clean lines. Very simple and very elegant."

Michael O'Connor: "She has a lot of stature in Hollywood and is not afraid of style and not afraid to be out there. Even for a mature woman, she isn't afraid of deep cleavage, and she likes jewelry and things with color. I have a piece that would be perfect for her from designer JW Currens."

Paster: "I dressed her when she wore Armani off-the-shoulder. I think she's one of the most beautiful women out there. I'd put her in a beautiful gold dress with little capped sleeves that shows the chest area. Maybe something by Badgley Mischka or Michael Kors."

Albanese: "She should stick with a solid color, something sexy and body-conscious, rather than overdoing the accessories and choosing a printed gown. I'd love to see her in navy or charcoal grey. A low-cut sweetheart neckline and something very fitted at the waist would be really flattering on her, something gorgeous from Donna Karan or Calvin Klein."

Bloch: "She's the chicest nicest woman, and so classy and elegant. She embraces fashion and dressing for her body, finding things that accent the waist and show off her cleavage. She loves Vivienne Westwood. She's very in touch with her sensuality and dressing is very reflective of sensuality.

Gidwitz: "She likes to keep it clean, she has a fabulous figure and she always looks like she's having fun on the red carpet. I see her in an Angel Sanchez or Lanvin, both of which would be age appropriate but not over the top but not stoic. She doesn't accessorize and keeps things relatively subdued and covered up. She is comfortable in black but would it would be great to see her in blue or a scarlet red shade.


The Client: Gabourey Sidibe (Best Actress nominee for "Precious")

Sarre: "David Meister is a designer she's favored in the past. She's worn him and looked fabulous. He'll custom-make her something for the biggest night of her life -- and she needs to have the most fabulous dress she's ever worn. She wears and loves color. She should go with an embellished metallic or dark jewel tone. Or maybe fuchsia, which is a big trend."

O'Connor: "I recently dressed Gabourey for the AFI luncheon (in a red dress and Erica Courtney diamond necklace). It worked because the shape of the pendants on the necklace was the exact shape as the neckline. She requires a piece that has some stature, like a statement necklace from Gem Platinum."

Paster: "This is her first time at the rodeo and it's really exciting for her. She should wear something fun and age appropriate, maybe from Cynthia Rowley or Jill Stuart in a young color like a darker purple, green or a pretty taupe."

Albanese: "I'd love to see her in red. It's not only a power color, it's her color-she looks stunning in it. She does a lot of bright jewel tones. Also, a long sleeve is more flattering on her."

Bloch: "Everyone who has been dressing her hasn't worked well with her body. I'd like to put a belt on her or something dark in the center to define the waist. She has a nice neckline -- maybe put her in something off-the-shoulder, maybe an empire neckline. A green color might be nice."

Gidwitz: "She'd be great in Naeem Khan. She should take the world by surprise and wear something by Viktor and Rolf, something that gets people to sit up and take notice."

UPDATE: Stylist Linda Medvene told USA Today that she took client Sidibe for a fitting at Marchesa this week. We'll see if she ends up wearing the designer on the big night!


The Client: Meryl Streep (Best Actress nominee for "Julie & Julia")

Sarre: "This is Meryl's time to shine. She should be in a classic, elegant, Old Hollywood look. I can see her in red, with a plunging neckline, and draped in back-maybe something from Armani or Valentino. It's her time to stand out in a bold color."

O'Connor: "With her fair hair, she can benefit from color. I'm bringing out some great rich, gemstone pieces from Chad Allison in the hope that I can meet with her."

Paster: "She dresses herself. I love that she wore Balenciaga for SAG. She's at the point in her life where she's working because she enjoys it and she's having so much fun. I'd put her in Alberta Ferretti or something soft and pretty, like a light coral or pretty pink."

Albanese: "I love that she doesn't feel she has to take crazy risks to look nice. I would love to see her in a color and something romantic, maybe an off-the-shoulder or one-sleeve that's long and flowy, leaving the other arm bare--possibly from Ralph Lauren or Donna Karan. But nothing too busy."

Gidwitz: "A simple Oscar de la Renta gown would be beautiful. I would love to see her in some really fabulous jewelry, that would be new for her, something showstopping and amazing. She tends to dress conservatively so I'd throw on a big jewel, probably a necklace."


The Client: Penelope Cruz (Best Supporting Actress nominee for "Nine")

Sarre: "She's worn a lot of black this award season so I believe she's saving her color for the Oscars. She would look great in plum or purple--maybe a one-shoulder dress, which are here to stay through next fall."

O'Connor: "Penelope really likes rich, vibrant color and looks great in it. I have a pair of earrings with her in mind from Leticia Linton, a new designer from Brazil. They have really great color gemstones set in platinum -- perfect!"

Paster: "Penelope is a vision. She did the princess look last year and would look great in something fun and sexier, maybe in a lighter color. Elie Saab would be gorgeous and she does well with Alaia."

Albanese: "No more black! She has worn black to the last two award shows. I'd love to see her in a power color. With her skin tone she can wear yellow, orange, or red. She's been looking kind of sweet; I would love to see her in something vampy, maybe in Basel Soto (a Paula Abdul repeat offender!)"

Bloch: "Vintage is brilliant for her. I love that she saw a gown and bought it [for last year's Oscars] -- it's a great story."

Gidwitz: "I would love to see her in vintage -- she's worn Lily et Cie -- or in a saucy but elegant, body conscious concoction by Fendi, Galliano or Dior. Possibly a bias cut with a fabulous spilling bottom from knee down in pink coral. She wears ruffles tulle very well.

And the Stylists had a few additional Oscar night predictions for other A-listers:

Mary Hart
"I'm partially dressing Mary Hart from Entertainment Tonight. She's actually letting America act like her stylist and pick her Oscar gown for her." --Sarre

Angelina Jolie
"If I had a chance to work with Angelina Jolie, I would have a little more fun with her. She usually just wears a black gown or something simple. I would up the ante a bit. I'd love to see her in something fun like Christian Dior." --Paster

Cate Blanchett
"Cate Blanchett will probably end up wearing Armani, which she's been wearing and it's been suiting her well." --Paster

Nicole Kidman
"Nicole Kidman took a risk for the SAG awards and wore something that wasn't so important. She dresses beautifully but needs more drama -- something fun like an Oscar de la Renta." --Paster

"I would love to see Nicole Kidman in Alexander McQueen. She also looks beautiful in L'Wren Scott." --Gidwitz

Anne Hathaway
"Anne Hathaway would look beautiful in Valentino. She's a huge fan and she wears it beautifully. I can also see her in Marchesa but that's a safer red carpet option." --Gidwitz

Kate Hudson
"I would love to see Kate Hudson in something fabulous by Givenchy, but not white since she just wore it. She's fair but she can tan so she looks great in yellow, black or white." --Gidwitz

Maggie Gyllenhaal
"I would love to see Maggie Gyllenhaal take a risk on the carpet this year. She should push the envelope in Gaultier, Lacroix or even Emmanuel Ungaro." --Albanese

Anna Kendrick
"I'm praying Anna Kendrick wears her hair down. I would love to see her in stark white, Kelly green or navy, from Dolce and Gabbana, Elie Saab, or Emilio Pucci." --Albanese
