Yes, you read that right, One size fits all jean brands! How could this be when getting the right size jean has been the plight of so many women like forever?

I often talk about fabric technology and this is a great example where the denim mills have created denim that can stretch & bounce back so much so sizing can be for multiple sizes. The perfect way for us to be more sustainable is by wearing our jeans for longer and brands to reduce the sizes on the shop floor.

I know it’s hard to believe but yes there are denim brands offering styles that stretch over ( literally) 4 to 6 sizes, so if you’ve put on a little weight over lockdown these are the jeans to be wearing!

Check out the denim brands below for true sizing enlightenment! It’s a true game-changer when buying jeans that fit

  1. Is this just a blog about jeans. How the heck do you actually buy anything. I just wanted to order a pair of jeans. I’ve spent a half hour clicking and reading and scrolling but can’t find a place to buy the jeans. Geez. I’m outta here!

  2. Have you read The Sisterhood Of The Traveling Pants? Or seen the movie.

    They find magic jeans that fit all four friends in a vintage store.

    Cute movie/book especially if you have a tween at home!

    Completely reminded of it by this blog!
