No matter if you’re preparing for a fashion event or a weather event — you’re going to need a good jacket.
What would become the modern jacket as we know it began as a strictly professional item. A lot of the vintage and designer jackets (and coat styles such as the Navy-inspired peacoat) in our closets were likely popularized by soldiers who battled aggressive climes with their regulation field jackets, bombers and parkas buttoned or zipped to the chin. Indeed, keeping troopers comfortable guided the design of the military surplus garments that have often become buzzy fashion trends. But now, jackets add far more than warmth to our wardrobe, and we hunt down outer layers branded with peerless fashion labels.
Fashion’s most iconic creations, despite their age, remain modern: Biker jackets originated in the 1920s, Balenciaga’s celebrated puffers are steeped in a tradition of down coats that began in the 1930s and your vintage denim jacket has come an even longer way, from California Gold Rush to wardrobe staple. Jeans bequeathed jean jackets during the 1880s, thanks to Levi Strauss, who crafted the former as a durable garment to be worn by miners and railroad workers. Later, jeans and jean jackets became synonymous with nonconformity and rebelliousness — with fashion legends such as actor James Dean in the 1950s and model Veruschka in the 1960s and ’70s leading the indigo-toned charge.
Another fashion rebel, Coco Chanel, used the classic tweed jacket to introduce more comfort and mobility into women’s daily lives. Debuting in 1954 and based on a cardigan, the groundbreaking Chanel jacket forever changed what women wear. The garment reacted against the fitted, constricting styles of Christian Dior’s New Look, which, as Chanel saw it, was making women dress like decorative objects.
On 1stDibs, find bold collections from cutting-edge contemporary designers who’ve taken the classic silhouette of the jacket to new heights or build out your array of vintage treasures (denim or otherwise) with dazzlers from Yves Saint Laurent, Gianni Versace, Moschino and more.
Costumer to the stars Ray Aghayan brought the famed painting to life with his spectacular design.
From handbags and heels to jackets and jewels, Sharon Coplan Hurowitz has a deep admiration for (and collection of) all things Chanel.
Jeriana San Juan explains how she undertook the intimidating project of designing costumes for the new Netflix series about the New York fashion legend. (Hint: She found vintage Halston on 1stDibs!)
Once considered a controversial item of clothing, fashion designer Sonja de Lennart's creation is now a bona fide classic.
The classic tweed garment has been a wardrobe staple of chic women around the world since the 1950s.
Amanda Benchley and Bridget Moynahan teamed up to explore the relationship between powerful women and their most significant footwear.
This year's Costume Institute exhibition is all about embracing the eccentric.
Ballrooms, Bar Suits and British royals — in a sweeping exhibition, the London museum looks back on 70 years of the French fashion house, as well as its illustrious founder and his fondness for the United Kingdom.
