Dolce Gabbana for sale on 1stDibs

Shapely lingerie models, animal and floral prints and the Mediterranean heritage of Sicily have come to define the romantic and sensual style of Dolce Gabbana, a leading international brand that from its earliest days of corsetry, copious lace and provocative silhouettes has challenged fashion with an audacious vision for femininity.

After meeting in Milan in 1980 while they were both working for Italian designer Giorgio Correggiari, Domenico Dolce (b. 1958) and Stefano Gabbana (b. 1962) would go on to establish their eponymous fashion empire in 1982. Three years later, a breakthrough for the duo materialized in the form of an up-and-coming talent showcase at Milan Fashion Week, where they unveiled an approach to fashion design that broke sharply from that of the era’s reigning Italian houses. By then romantic partners as well as a business, Dolce Gabbana were outsiders. Soon, their distinctive garments — sexy, feathery skirts and stretchy jersey evening dresses that favored full figures — demanded the fashion world’s undivided attention.

Though Dolce Gabbana forged a path in womenswear that would take shape with a 1986 collection called “Real Women,” the brand’s offerings broadened quickly to encompass knitwear, swimwear, lingerie, ready-to-wear, menswear and perfume. In the early 1990s, Madonna helped catapult the luxury house to international stardom: The renowned singer and actress famously tapped the brand to create the looks for her 1993 tour “The Girlie Show.” It saw Madonna working closely with the designers and even starring in their ad campaigns. Dolce Gabbana has continued to develop a high-profile clientele that includes pop sensations such as Beyoncé and Lady Gaga. The latter donned Dolce Gabbana’s armor corset dress in the music video for her hit single “Paparazzi.”

Rather than following the rapidly changing trends of fashion, Dolce Gabbana have instead held to their close-fitting tailoring and decadent designs. The house continues to work with recurring themes such as the culture of Italy and Catholicism, which is manifest, specifically, in their widespread use of black lace, a fabric that references the dresses worn by Sicilian widows. The duo is also inspired by Italian cinema and its icons such as Gina Lollobrigida and Sophia Loren; in 2015 they introduced the Sophia No. 1 lipstick in her honor.

Although Domenico Dolce and Stefano Gabbana separated as a couple in 2005, they continued their business as a creative partnership. In 2012, they closed their less expensive D&G ready-to-wear line to focus on exclusive extravagance, such as their Alta Moda custom pieces. Today, Dolce Gabbana maintains a popularity with a wealthy clientele, and the house’s 2020s collections have featured technological experiments that update traditional styles, such as a bouclé jacket with a pixel-like pattern, as well as throwbacks to the 1990s fashion that made the brand a household name.

Find vintage Dolce Gabbana handbags, day dresses, shoes and more on 1stDibs.

Finding the Right Clothing for You

Start building your collection of covetable and iconic vintage clothing today — no matter where you roam, there is a curated selection of designer dresses and gowns, sweaters, shirts, dazzling shoes and more on 1stDibs that will keep you covered in the hottest styles from head to toe.

From elegant museum-worthy vintage Chanel dresses and jackets to audacious T-shirts and trousers from provocative punk designer Vivienne Westwood, one thing is abundantly clear: If the clothing for sale on 1stDibs could talk, it would certainly make a statement. 

For fashion lovers, the 1990s have become associated with styles adopted by today’s supermodels and influencers — think John Galliano and Roberto Cavalli — but maybe ‘80s accessories are among your (guilty?) pleasures. 

Playful, boldly colored coats and outerwear from Moschino, Ralph Lauren and other titans of the era can take a simpler ensemble to the next level, while chic and practical suits from the likes of Christian Dior and Balmain endure for haute couture advocates and beyond. 

And vintage is the name of the game on today’s red carpets, too. Celebrity stylists are turning to archival pieces created by the likes of Bob Mackie, Thierry Mugler and Jean-Paul Gaultier as alternatives to new gowns plucked straight off the runway. Wearing such sought-after items gives celebrities instant allure and suggests a personal style that’s not only achingly glamorous but intellectually informed and influenced by a love of craftsmanship. 

Those seeking contemporary luxury looks and in-demand street-style fits can indulge in designs by Bottega Veneta, Miu Miu and Loro Piana, while pieces from Gucci, Yves Saint Laurent and Versace endure as examples of fashion’s most covetable goods. 

The future — and glamorous past — of fashion is yours for the wearing. Find vintage clothing and accessories for sale on 1stDibs, including designs by Balenciaga, Valentino, Celine, Loewe and more.
