Sewing pattern blouse Cecilia is a special model with attached pleats at waist height. The top has princess seams in the upper part and from the waist the named pleated part. This makes the blouse beautifully feminine and figure-hugging.

The pattern is perfect for upcycling a men's shirt. Modifying the peplum and adding the ruffle in the armhole is a great way to replicate the cut.

To the pattern Cecilia

In order to get a little insight and some understanding, we have prepared a video for you here.

In my example I used a men's shirt in size 52 and the Cecilia pattern in a 38.

In order to start cutting, you must first unpick your old seams from your shirt. The sleeves,… well as the yoke must be unpicked. I really recommend unpicking the seams here and not cutting them open. I used every inch of the seam allowance in the pattern to be able to cut out all the pattern pieces


Cut out the pattern pieces from your outer fabric. Lay the fabric right side up. The pattern pieces should all be face up. Always align the grain arrow on all pieces in the same direction and parallel to the selvedge of the fabric. Transfer all the notches from the pattern through a 3mm long incision with scissors or chalk. Pinch the seam allowance in the fold of the fabric because this is always a center. Markings define positions of dart ends, pocket positions, and much more. Transfer these either with chalk or pins.

Take a look to see if the pattern pieces of the top fit your open shirt. Then draw a horizontal line to determine the length of the peplum.

Now draw your pattern pieces on the shirt and make sure that the front part rests against the button placket so that you can adopt it. You need from fabric:

  • 1x front part with peplum
  • 2x front side panel
  • 2x rear side panel
  • 2x back
  • 4x sleeve ruffle
  • Bias tape to bind the edges

Sewing instructions:

To sew this dress you will need a sewing machine and an overlock sewing machine, alternatively you can use the zigzag stitch on your sewing machine to overcast the raw edges.

In addition to the description, the colorful lines in the pictures show you where a seam needs to be sewn or something to be glued.
When sewing, pay attention to the seam allowance included in the pattern. Seam allowances that are not specially marked are 1 cm wide!
Happy sewing!

We start by closing the dividing seams and the side seams. I chose right-left seams here, but you can also simply neaten your seam allowances.

The front dividing seams are then closed. Now you can gather your peplum at the top edge and…

... sew to your bodice.

In order to be able to sew the ruffle insert, it is first cut out of the remaining sleeves. You can set the length yourself. I used a length of approx. 40 cm and a width of 5 cm.

Lay your pattern pieces right sides together and sew them in place. The sleeve ruffles can then be turned over and topstitched.

The finished ruffle can now be placed, right sides together, in the armhole and fixed with an auxiliary seam.

Now all that's missing is the edging for the neckline and armholes. You cut this out...

… to the other remaining sleeve and then overturn the still open edges with it.

Your CECILIA is ready !
