The One Shoulder Tank is a new modern classic. It combines a chic asymmetric neckline with the casual ease of a classic tank.

WATCH THE VIDEO to see what's in this sewing pattern:



    The One Shoulder Tank sewing pattern combines wide binding with our 2 most popular t-shirt silhouettes: semi-fitted & flared with hem band. It has been intentionally designed it to give maximum coverage across the décolletage.  

    You can even add a beautiful ruffle along the neckline of your tank.  

    Make this versatile tank a standout in your wardrobe. Pair it with everything from skirts and denim to tailored trousers or palazzo pants.

  • Bindings must have elastane (or Lycra or Spandex) & good recovery.

    SHELF BRA: In the Get Creative section of the tutorial, you'll find instructions on how to add a shelf bra.

    A shelf bra is more like a crop top. It will not provide the same support that a bra is engineered to give. It's still pretty awesome though. Wear the tank/shelf bra combo braless or, my personal preference, with a strapless bra underneath the shelf bra. I find that the shelf bra helps hold that up. As an added bonus, a shelf bra can help smooth out the lines from the bra.

    Most important is to ensure binding/band fabric has matched or greater resilience than both main & shelf bra fabrics. 

  • Shelf bra suggestions include self fabric & swim lining.
  • 2.5-4cm (1-1.5") elastic if adding shelf bra.

    Super cute and sew easy!

    I am totally in love with this pattern! The one shoulder fit is beautiful and while wearing it I don't feel like it's slipping. It's also one of the quickest sews! And the binding was surprisingly easy to construct and gives a beautiful finish!

    Lovely stash buster

    What a cute tank! I just love the flounce & wide binding! I can't wait to try out the other versions.
