Choose extra-large frames, as they shield the fragile skin around the eyes from skin cancer and aging. The perfect sunglasses don't have to cost a lot but should block 99 percent to 100 percent of UV rays for maximum protection against skin cancer and cataracts, according to the American Cancer Society.
"If you can look like Jackie O and still protect that sensitive skin around your eyes, why not?" fashion guru Goodkind says.
Dermatologist Day ups the ante on the protection side at the cost of a little style. "Ideally, the best sunglasses are the ones that wrap around the side a little bit and block the sun from coming in, the ones you wouldn't be caught dead in," she says, laughing.
She recommends wraparounds, especially for her Botox patients, to keep them from squinting.
Big, wide-brimmed hats, like the ones seen in the Marc Jacobs collection, screen the areas most exposed to the sun and so the most vulnerable to skin cancer -- the scalp, face and forehead, neck, ears and eyes.
"The head and the neck account for 80 percent of all basal skin cancer, the most common form of skin cancer," Chon says.
Huge big-brimmed hats give attitude. "They're another way to make a statement," Goodkind says. "Big-brim hats go with a spring attitude, a resort attitude, and if you're looking to add a little personal style, it's a great look."
But again, pay attention to the weave, especially if choosing a straw hat. "If the weave is loose, everything goes right through it," Chon says. "A fabric hat will probably be more opaque to light."
The MD Anderson Cancer Center recommends holding your straw hat over the ground and examining the shadow it casts. If light speckles the shadow, toss the hat.
They're not just cover-ups anymore, even though "any extra help you can get at the beach is great," Chon says. And if they have long sleeves, all the better.
"You get a lot of reflected light from the sand or just by sitting by the water," Chon says. "Even under an umbrella, people still get sun."
But take care not to pair a tunic with full-length pants. "It can look like pajamas," Goodkind says. Either belt it, or pair it with another runway highlight -- leggings.
"It's all about proportion," Goodkind says. "If the tunic's longer at the top, you might go with a cropped or more Capri pant at the bottom."
Lighter than most pants, leggings have been a fixture on the runways since their tentative comeback in 2005. "We saw a lot of those skinny, skinny pants, which translates to the legging, no question," Goodkind says.
Slip them on under a tunic or a dress, and they're a leg-saver.
"More women develop skin cancer on their legs than men do, probably as a result of more sun exposure over time that comes from wearing shorts and skirts," Chon says.
"Leggings are pretty helpful, but they cut off right below the knees, so you have that area still exposed, but you can wear the ones that go right to the ankle."
The mini has yielded to the maxi, which, along with leggings, is another leg-saver. And they morph easily from day to night, beach to street.
"I noticed very young women with very long dresses, and I'm happy about that," Day says.
