HACK: Cerena Yoga Waistband

Cerena Romper Yoga Waistband Hack

Hi, it’s Miranda from I Have Purple Hair. Today I’ll be showing you a neat hack that you can use with the latest pattern, the Cerena Romper!

Lemme tell you something: I absolutely LOVE yoga waistbands. Why? Well…

  • They’re super cute,
  • They’re comfortable as heck, and
  • They’re crazy easy to make!

This fun project turns the lovable Cerena Romper into a more versatile pattern worthy of having in your apparel sewing arsenal. Easily adjusted for pants, gaucho, or shorts, this waistband hack is great for beginners and experts alike.

You can do this hack with any size in the Cerena range.

You’ll need the pattern first (get the ladies XXS to 5XL here, childs newborn to 12 years here, 18 inch dolls here, or save and buy the whole bundle here).

Measure yourself (or your model), then print your size and you’re ready to start…


  • Be careful not to stretch the fabric as you sew. Widen the stitch length a little so it’s easier to sew.
  • Make sure to use a ballpoint needle
  • I’m making a ladies’ XL, but this trick can be easily adjusted to fit girls and ladies of all sizes!

You’ll need:

  • Cerena Romper pattern
  • Ballpoint Needle
  • Rotary cutter and mat
  • Ruler or measuring tape
  • 1 – 2yds of knit fabric
  • Walking foot if using a sewing machine (optional)

Before You Start:

You’ll need a few measurements:

  • Waist Measurement –  Measure around your waist where you want the shorts to sit. I like mine just underneath my belly button, so I measured there. We want the length to be a bit snug so that the waistband won’t fall down, so no need to include a seam allowance.
  • Finished Height of Waistband – How tall do you want to your waistband to be when it’s all sewn up? Do you like a more fitted look or a scrunchy effect? I like somewhere in between, and measured mine to rise about 4.5″. Remember that the waistband will be folded over, so double your height measurement and add 1″ to allow for seam allowance.
  • Waist Measurement + Waistband Height = Waistband Fabric Piece (For example, I measured 38″ at my natural waist, and like a 4.5″ cuff, so my waistband fabric piece measured 38″ x 10″).


Step 1: Print out your pattern pieces and arrange them on your fabric. I was able to finagle the short patterns in XL and a waistband with about a yard of fabric.

Step 2: Follow instructions for sewing the Cerena Romper bottoms, making sure to include the darts.


Step 3: Fold your Waistband Fabric Piece in matching short edges, right sides together. Sew, making sure to use 1/2″ seam allowance. Now you have a loop! Your waistband piece will now be 1 inch smaller than your waist measurement (so it will stretch and fit snugly on your body when wearing it).

Step 4: Now, fold your Waistband Fabric Piece matching long edges, wrong sides together so that the seam is inside the loop, and it’s half the height it used to be. Lay flat and pin at 4 even points. Start with your seam and pin directly opposite. Mark the sides with pins. (I serged my raw edges together to keep the edges together easier because my fabric is thinner, but it’s not necessary)

Step 5: With your shorts or pants turned right side out, mark 4 equal sections at the top.

Step 6: Slide the waistband over the shorts/pants, matching raw edges and pins and ease your shorts or pants to fit Waistband Fabric Piece. Sew together.

Step 7: Hem bottom openings and you’re all finished!
