RAQUEL WELCH, 73
Some things never change! Nearly 50 years after kicking off her career playing the siren in 1966's Fantastic Voyage and One Million Years B.C., Welch proves her sex symbol status is still very much intact, wearing a curve-hugging animal-print dress at a September pre-Emmys party. We bet she can still rock the fur bikini that first turned her into a pin-up girl.

LYNDA CARTER, 62
It's a role so iconic, no actress has been able to fill it since: Carter's turn as Wonder Woman launched the former beauty pageant queen into superstardom in the late 1970s, and her fame has hardly faded. But in 2013, the actress is better described as the ageless wonder, still leaving revelers transfixed with her sharp cheekbones and bright baby blues at an N.Y.C. charity gala in October.

JANE FONDA, 75
Following her star-making turn in 1968's Barbarella, one sexy role followed the next for Fonda, whose portrayal of a high-class prostitute in 1971's Klute earned her a Best Actress Oscar. And only Fonda's fab physique could launch a 1980s aerobics craze, as millions bounced along to her workout videos. When The Newsroom star returned to the limelight in the 2000s in movies like Monster-in-Law, she still got cameras clicking – including at her November appearance at the United Nations Foundation Global Leadership Dinner. The ageless babe also earned a spot on PEOPLE's Most Beautiful 2013 list.

BARBARA EDEN, 82
Starring as the whimsical wish-granter Jeannie, Eden made many a boy's Dream come true on 1960s sitcom I Dream of Jeannie, for which she donned a crop top and harem pants, inciting censor issues over whether her navel should be seen. More than 40 years after the show went off the air, the star brought the outfit out of retirement for an appearance at May's Life Event charity ball in Vienna, proving she's still got the magic.

SUZANNE SOMERS, 67
The pigtails, the short shorts, the snorting laugh … the blonde beauty became everyone's favorite girl next door with her breakout role on 1970s sitcom Three's Company, and her famous legs helped make her the face of the Thighmaster (and landed her a gig in Playboy). Two decades later, Somers is still showing off her assets: The actress made Chrissy Snow proud when she donned a strapless cocktail gown for the Wallis Annenberg Center for the Performing Arts Inaugural Gala in October.

SOPHIA LOREN, 79
With her pouty pucker and ample, ahem, build, Italian beauty Loren became a Hollywood staple with a string of sultry roles, including 1958's Houseboat. Her Academy Award-winning performance in 1961's Two Women cemented her status as a serious dramatic star, but Loren never lost her alluring appeal, returning to the screen in 2009's Nine and stunning revelers with her November trip down the red carpet at the Pirelli calendar's 50th anniversary event in Milan, Italy.

JACLYN SMITH, 68
With the face of an angel – Charlie's Angels to be precise – Smith was transformed into an overnight sensation following the series's 1976 premiere – cue the dolls, lunchboxes and posters! Later she parlayed her enviable style sense into a Kmart clothing line in the '80s, one of the first celebs to brand her name. Fast-forward to present day, and Smith remains her best advertisement, working a slinky LBD at the April 2011 Odyssey Ball.

JOAN COLLINS, 80
When she joined the cast of Dynasty in 1981, Collins skyrocketed to fame as the soap opera's resident sexpot, a quality she later put to use as the author of a series of erotic novels. More than 20 years later, the brunette babe continues to set hearts racing as she bats her extra-long eyelashes and smiles coyly from red carpets, including February's Vanity Fair post-Oscars party.

CATHERINE DENEUVE, 70
With her doe eyes and long blonde hair, the French femme gained international stardom in 1967 after starring as a beautiful housewife who works at a brothel in Belle du Jour. The incredibly sexy role turned Deneuve into a fixture on the minds of men, particularly high fashion's elite, with Yves Saint Laurent having considered her a muse and Marc Jacobs casting her in Louis Vuitton's 2007 ad campaign.
