Collecting fragrance flacons: so musty! The latest invention from Cartier offers a better approach: an elegant gold case that resembles a vintage cigarette holder and contains a one-ounce bottle of Déclaration, Les Heures Voyageuses Oud & Oud, or another best-seller of your choosing. Lacquered with the house’s motif of a panther tiptoeing in front of a grove of cypress trees, it’s fitted with a magnet inside to keep the bottle snugly in place. This accessory was designed to be admired, so rather than leaving it on a vanity table, give it a chance to shine. It fits perfectly in an evening bag, so take it out on the town and spritz freely. Don’t blame us if everyone weeps with envy. ($1,022 for the case and $102 for a one-ounce bottle of fragrance, cartier.com) —Ashley Baker

As a young art student, I would become lightheaded at the prospect of an economy-size box of colored pencils. Even now, opening a fresh tin of Caran d’Ache gives me a nostalgic thrill. Hermès takes that simple pleasure and transforms it into a whole new level of luxury with its new Trait d’Hermès, a limited-edition collection of 40 timeless and emblematic makeup pencils. The orange box holds 24 for the eyes and 16 for the lips, plus one black liquid eyeliner and the world’s most glamorous sharpener. For those who don’t need the full rainbow, the pencils are sold in smaller sets of 4 and 12. Now to learn to color within the lines. ($2,192; hermes.com) —Christina Grasso

How many times has someone told you they found the perfect white T-shirt? And how many times is it truly perfect? They’re either too thin, too stiff, too boxy, too bunchy, too saggy, or just too boring. But when Karla Welch, the impeccable stylist who works with Justin and Hailey Bieber, Tracee Ellis Ross, and Sarah Paulson, comes up with the perfect white T-shirt, well, now we’re talking. Welch worked with Michael Stars to create this wonder. It has just the right amount of heft, an excellent, finely ribbed neck—crew, not V—and sleeves you can roll up for a bit of swagger. Sales benefit Welch’s Period Abundance Foundation, which raises awareness about period poverty. ($48, michaelstars.com) —Linda Wells

My Ziip device is about the size and weightof a croissant. It beeps, and then its two nodes pass electrical waves through the surface of my skin up to 60 times per second, alternating between microcurrents (small waves that stimulate facial muscles) and nanocurrents (smaller waves that bolster skin’s collagen industry). It was created by Melanie Simon, Montecito’s “electric aesthetician,” as an at-home version of her signature treatment, and earlier this year was acquired by the U.K.-based Currentbody, who helped fine-tune the device to be lighter and easier to use. The app comes pre-loaded with treatments for skin lifting and even spot treating, each featuring a tutorial with Simon herself. Or you can just press a button and go to town with shocking ease.

Everyone who’s freaked out about A.I. needs to relax—and Remedy Place has just the thing for this particular anxiety: an A.I.-assisted, robot-administered massage. If that sounds like the least soothing idea on God’s green earth, stick with me. Having submitted my knotted muscles to its bizarre white arms at the new Remedy Place in SoHo, I can attest; it’s sublime. Here’s how it works: You dress in the leggings and top provided by the spa, lie on the massage bed, and the machine measures your body and offers a variety of pressures. The robot arms do the usual massage-y things with paddles that resemble warm hands. My favorite part of the experience was the lack of small talk. I never heard any complaints about my tight traps and never felt compelled to praise the robot or worry that it might get too friendly. Remedy also offers cryotherapy, ice baths, infrared and traditional sauna rooms, red-light beds, hyperbaric treatments, and IV drips. You’ll emerge feeling as coddled as a tech billionaire but without the terrible haircut. ($90 for 30 minutes, remedyplace.com) —Linda Wells

Burberry had one of the loveliest makeup lines around, all very English rose in soft, flattering colors created by makeup artist Wendy Rowe. And then, gradually and mysteriously, it disappeared from the United States. Now the reconceived line has returned to nordstrom.com, Selfridges, and burberry.com. Its especially appealing foundation has a new formula that involves Trench Protect Technology and “weather protection.” Gimmicky, maybe, but it delivers water-resistant coverage that lasts up to 24 hours—in case you’re planning on heading from work to a rave in the rain. Not exactly my style, but I appreciate the foundation’s ability to stay on without creasing and even survive an overnight flight. The group of well-chosen shades of lipsticks, which come in satin and matte finishes, is also beguiling. I plan to cinch my trench, slick on Delicate Rose No. 14, and head to tea at Claridge’s.
