Black knit dresses
25 Unions presents a collection of black knit dresses. We offer over 25 models in various silhouettes, styles, and lengths, created by a team of professionals who understand true beauty. Our goal is to ensure that every woman, regardless of body type, can wear stylish and fashionable clothing—so there's plenty to choose from.

Which black dress to choose: knitwear as a wardrobe must-have
To paraphrase the great Coco Chanel: every woman should have a black knit dress in her wardrobe. Here are three reasons why:
- Dresses have been a foundation of women’s wardrobes for centuries.
- Black is timeless, elegant, practical, and beautiful.
- Knitwear is a must-have: it's the right choice, it's iconic, it’s how it should be.
Knitwear has long secured its place in our wardrobes due to its comfort, timeless style, and versatility across fashion genres. This fabric allows for the creation of dresses suitable for any season. Even the simplest casual model can be instantly transformed into a striking evening outfit with the right accessories. Knitwear is easy to care for, maintains its perfect look for a long time, and once it’s served its purpose for outings, it can still offer comfort as loungewear.
Trendy styles: black knit dresses for any occasion
If the phrase "black knit dress" already describes an item in your wardrobe, that means you’ve got taste, style, and a great way to look stunning in any situation by switching up accessories or adding new elements. But that shouldn’t stop you from browsing and buying new fashionable designs from 25 Unions—each of them unique and beautiful.
Black knit dresses with long sleeves are a perfect classic. We offer at least 10 different models, including:
- Full-length, figure-hugging dresses with sleeves down to the fingertips;
- The same cut in various lengths—knee-length and ankle-length—with a cuff detail on the bodice that transforms into a unique neckline;
- Short versions with a bateau neckline and flared sleeves;
- Form-fitting styles with a striking and original décolleté;
- Bodycon dresses with interesting twisted details revealing the midriff.
Each of these dresses follows the latest fashion trends and deserves a place in your wardrobe.
We also offer short black knit dresses, perfectly aligned with the legacy of the iconic couturier. One of our bestsellers is a sleeveless design with a square neckline that’s not too deep. It’s perfect for an evening walk in summer with flat sandals. Swap those for heels and add a delicate necklace, and you’re ready for a cocktail party. Add jewelry and a statement hairstyle, and it becomes a glamorous evening outfit. Want to wear it to the office or a business meeting? Just add sheer tights and a blazer in any color.
You can also choose a black knit midi dress. One of our most popular is a ribbed knit model that gently hugs the body. It’s enhanced with a decorative hem detail and has cap sleeves. This dress can be the centerpiece of your wardrobe, and with different accessories in a range of textures and styles, it offers endless ways to refresh your look while always staying chic.
If you want to embrace your inner femme fatale and highlight your sensuality, opt for a black knit dress with a slit. One of our standout models features a body-hugging silhouette, mid-calf length, long sleeves, and a teardrop-shaped cutout on the bodice. The sophisticated design is a statement in itself, but you can elevate your look for a special evening with bold jewelry and on-point makeup.
