If you’re still rightly charmed by the look of Catherine Deneuve’s Séverine Serizy in Belle de Jour 52 years after its release, then this day dress is a legitimate investment. Hedi Slimane, Celine’s creative director, is a proven master at elevating an elementary idea into a work of art, and this frill-collared frock is a testament to his talent. Made of an acetate-silk blend and festooned with covered buttons, it has a youthful spirit but an entirely mature presentation—just like Deneuve. ($3,450; celine.com)

Thank goodness that not every over-the-knee boot reminds us of Julia Roberts’s not-for-everyone attire in (the first half of) Pretty Woman. Max Mara’s demure Beaton style covers the knee but stops there, and the modest heel offers the right amount of height, ensuring that one can comfortably walk the streets without ever resembling a streetwalker. Your dignity—and podiatrist—will thank you. ($1,245; maxmara.com)

In our eternal quest to perfect the art of travel, we’ve developed a dependency on Paravel’s packing cubes.

You can try to avoid fall’s ubiquitous mini-bag trend, but why? At first glance, Fendi’s Nano Baguette appears, perhaps, an absurd size, but a closer look reveals its utility. This picayune version of the brand’s popular Baguette bag can be worn as a cross-body, fastened onto a belt, or even tacked onto a larger piece of arm candy, which was how it was shown on Fendi’s runway. It’s perfectly suited for evenings out and will easily stash the essentials—credit card, phone, lipstick, and a wad of small bills. Tipping generously is the very best look of all. ($650, fendi.com)

At the recent New York Fashion Week, Matthew Adams Dolan emerged as the most discussed young designer in town. Conveniently, his fall collection has just arrived in stores, allowing us to put our ardor into action. The very best piece is this dramatic blouse, which can be worn in all sorts of intriguing ways—belted with leggings, jeans, or even Bermuda shorts, worn loose to the office over a trim midi skirt … Supporting the next generation is generally a good look, but in this case it’s especially smart.
