Why you'll love it

  • Soft knit: the acrylic yarn feels warm and comfortable all day.
  • Side slit: it makes walking easy and adds a flattering detail.
  • Pull-on style: no zips or buttons, just pull it on and go.
  • Wide size range: available from S right up to 5XL.

Perfect for: cold office days, winter weekends, Christmas shopping and cosy evenings in.

Curveline started with a simple belief. 🤍

Every woman deserves beautiful clothing in her size.

As a brand created for curvy women, we were tired of seeing beautiful styles that did not include every size. So we created a place where women never have to wonder whether their size exists.

What started as a simple idea quickly became something much bigger than we ever imagined.

Because of women like you. ✨

Your support, your orders and your belief in what we are building have helped Curveline grow into something truly special.

And now, we are moving into a bigger home. 🤍

To celebrate this exciting new chapter, enjoy up to 70% off sitewide while stocks last.

Wore this out for coffee with a friend and ended up staying for lunch! It's nice having something I can just throw on without spending ages deciding what to wear. Really pleased with how it looks on me.

I wanted something I could wear to lunch with the girls without feeling too dressed up, and this outfit is just the ticket! The pleated skirt gives it a smart finish, but it still feels like something I'd happily wear all day.

I couldn't wait to open my parcel! I've been after a chunky knit like this for ages, and the neutral shade is exactly what I wanted. Already thinking of a few outfits to wear it with!

I wasn't planning on buying another cardigan, but here we are! Really pleased with this one. It's just the sort of thing I can pop on for the school run or a quick trip into town.

I nearly went for my usual black coat, but I'm so glad I chose something brighter this time! Wore it out at the weekend and felt really good in it. Sometimes a little change is just what you need!
