Boiled Wool Jacket For Sale on 1stDibs

You are likely to find exactly the vintage or contemporary boiled wool jacket you’re looking for on 1stDibs, as there is a broad range for sale. Our collection includes a variety of colors, spanning Black, Blue, Brown and more. Making the right choice when shopping for a boiled wool jacket may mean looking at versions that date from different eras — you can find early iterations from the 20th Century and a newer version made as recently as the 21st Century, both of which have proven very popular over the years. Making an accessory such as this has likely been a part of the legacy of many fashion designers, but those produced by Chanel, Azzedine Alaïa and Geoffrey Beene are consistently popular. Finding a boiled wool jacket for sale for women should be easy, but there are 3 pieces available to browse for men as well.

How Much is a Boiled Wool Jacket?

The price for a boiled wool jacket starts at $350 and tops out at $3,949, and on average, selling for $797.

Finding the Right clothing for You

From museum-worthy vintage Oscar de la Renta evening dresses and jackets to audacious T-shirts and trousers from provocative punk designer Vivienne Westwood, one thing is abundantly clear: If the clothing available 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 Galliano and Cavalli — but maybe ‘80s accessories are among your (guilty?) pleasures. Playful, boldly colored coats and outerwear from Moschino 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 Chanel remain classic for haute couture advocates and beyond. By exploring the vast array of vintage collections on these pages, you can transform your closet into a retreat that is as retro as it is royal. 

Velvet cocktail dresses and silk evening gowns designed by French-born American couturiere Pauline Trigère — who dressed Wallis Simpson, the Duchess of Windsor — have proven timeless since their mid-century debut, while an overcoat by Alexander McQueen is the perfect finishing touch. In fact, an emerald one stays in rotation for Kate Middleton, Duchess of Cambridge.

Those seeking modern high-fashion brands are also in luck. Turn your day-to-day into a runway with selections from Dolce & Gabbana, Yves Saint Laurent and Versace or complete that fresh look with stunning footwear classics from the likes of Gucci and Christian Louboutin. The future — and glamorous past — of fashion is yours for the wearing. 

Build your collection of covetable and iconic vintage garments by shopping on 1stDibs. No matter where you roam, our diverse apparel and accessories will keep you covered in the hottest styles and comfiest black hoodie imaginable.
