Tired of jumpers that either itch or look too casual? Meet Kowalski™ | Calm Button-Up Jumper.
My dear... How many times have you reached for a jumperthat started to pinch after a few hours, clung to your shoulders, or simply didn’t look as elegant as you wanted? I know that feeling. As we age, we want to feel comfortable – but without sacrificing a feminine, polished appearance.
That’s why, when choosing gems for the 20th anniversary of Kowalski Warsaw, we knew that Kowalski™ | Calm Button-Up Jumper was a must-have. The soft fabric gently wraps around the silhouette, and the subtle buttons at the neckline add a feminine, timeless character to the whole piece. In this jumper, you should simply feel at home – warm, light, and elegant.

✔ Subtle buttons at the neckline

✔ Loose fit that forgives
Beautifully drapes on the silhouette without clinging too tightly. Comfort all day long – without sucking in your stomach.
✔ Calm color palette
Available in soft, timeless shades that match everything in your wardrobe.
✔ Absolute versatility

Worn.Loved.Reviewed.

Better than expected
I don’t usually leave reviews but this genuinely surprised me. The fit is lovely, the fabric feels nice against the skin and it looks really put together on.

Exactly what I needed
This fit is perfect and the fabric feels so soft. Very happy with the quality – will definitely order again.

Flattering fit
Really pretty on. Only reason I’ve done 4 stars is I personally would have liked a tiny bit more room, but overall it still sits beautifully and looks expensive.

So comfortable and flattering
Feels amazing on my skin and fits just right. Haven’t felt this confident in a while!

Got asked where it was from twice
Wore this out last week and two separate people asked where I’d bought it. It has that effortless dressed-up feel without looking try-hard.

Great customer service
Had a question about sizing and got a reply within an hour. Friendly and helpful – made the whole experience stress-free.

Helpful customer service
I messaged before ordering because I was unsure on sizing and got an actual useful reply instead of a generic one. That made a big difference and the size they suggested was right.

Lovely quality
Better than expected. The material feels premium and it looks even nicer than the photos.

Super fast delivery
I ordered on Monday and it arrived the next day! Really impressed with the service and the packaging was lovely too.

So chic
This is exactly the sort of thing I’m always hunting for and rarely find. Clean, feminine, flattering and easy to style without overthinking it.
