Katty ruffle trim tie back blouse – free PDF sewing pattern

katty ruffle trim tie back blouse free sewing pattern


Although summer is coming to an end, the weather is still so hot – and I am still in the mood of making a feminine, flirty garments. This design is inspired by some photos I found on Pinterest, and I could not buy one as the shopping website does not have a larger size for me. Anyway, I think it looks lovely, especially the bow tie at the back of the blouse, so I better make myself a piece that can fit me well. I name it the Katty ruffle trim tie back blouse!

As usual, my pattern is made in 10 sizes from XXS to 5XL, so you will find yourself a suitable size. You can also lengthen or shorten the hemline to get your desired length – you can even make a dress from this pattern.

The pattern is made using layered PDF, please check for your desired size before printing so you won’t waste your paper. I have included a first page with many details about sizing and printing, so please first read the first page and make sure you know what size you need! If you still do not know how to print a layered PDF, please check for the instruction here.

You can print this using your home printer and A4/Letter paper. I calculated the printing area so that you will be able to use either type of paper to print the pattern out perfectly. Always print the first page first and check with the test square if you are printing at the right scale before you print out the whole pattern – avoid waste of ink and waste of paper, save the earth!

Some PC may print smaller than actual size even when you choose 100% scale – I don’t know why this problem exist, but my HP laptop cannot print true to size. I have to scale up to 103% to get the right size. You may need to check with your PC to see if it prints true to size, if not, scale up a bit.


You will need

  • Fabric of your choice
  • Some bias tape
  • Some narrow elastic
  • Scissors, pencil or fabric marker, ruler, pins
  • Sewing machine or needle and thread
  • Printed pattern

What fabric can be used for this project? You can make a top from any kind of fabric, and as it is intended to keep you cool in the summer, opt for soft 100% woven cotton or linen fabric.

How much fabric do you need for this piece of garment? Not too much. In general, a yard of fabric is enough. But to be precise, you may need to check how much fabric you need before buying. It will depend on the selected pattern size, the width, and design of the fabric you plan to use. Just to be sure, print all the paper patterns and lay them out at the width of fabric you plan to use (usually from 90 to 150 centimeters or 35 to 60 inches). Measure how much fabric you will need. Don’t forget to account for pieces that need to be cut multiple times and pieces that are cut on the fold.

Cutting instruction:

After printing out and taping all the pattern pages together, you will get something similar to this image:

You will see that there are 2 sets of lines on each pattern size. The inner lines are sewing line (and you sew along these lines), and the outer lines are cutting lines (you cut the fabric along these lines, remember the folding lines where you have to fold the fabric before cutting). The distance between sewing line and cutting line is seam allowance, and it varies from point to point. For example, the side seam allowance is about 1/2 inch (1.2cm), and seam allowance at hemline is 1 inch (2.5cm). This is the reason why I do not remove the sewing lines from the pattern. Please use it as a guide to know how much seam allowance you need to give at each seam.

Fabric will be cut into following pieces:

  • Upper Front: cut 1 piece on the fold
  • Lower Front: cut 1 piece on the fold
  • Back Shoulder Strap: cut 2 pieces
  • Upper Back and Tie Ribbon: cut 2 pieces
  • Lower Back: cut 1 piece on the fold
  • Ruffle Trim: cut 2 pieces

Make sure to mark all notches and other design features such as pleats etc. from the pattern piece onto your fabric. When sewing the garment, pay attention to notches, they must match up.

Sewing instruction:

1. Serge the fabric to prevent fraying. If you use non fraying fabric (like knitted fabric), you can skip this step.

2. Press and sew to close the bust darts on the Upper Front piece.

3. Sew two parallel lines 1/8 and 1/4 inch from the upper edge of the Lower Front using longest stitch line. Pull the threads to gather the fabric so it matches the lower edge of the Upper Front.

4. Using the same method to gather the Lower Back piece (from the notch to the side) it matches the Upper Back piece (from the notch to the side). Leave the middle part between the two notches flat.

5. Place the Upper Front and Lower Front right side facing, pin and sew to join.

6. Place the Lower Back with one piece of the Upper Back, matching the edge and the notch, pin and sew. Repeat with the other Upper Back piece. Press the seam open. Sew a narrow tunnel on middle part of the Lower Back piece, insert a piece of elastic and secure it. Sew the seam allowance of the Upper Back to hem the ribbons.

7. Place bias binding right side facing the neckline. Pin and sew along the neckline. Turn the bias tape over and staystitch it. Cut off the excess tape. Place the Upper Front and Shoulder Strap right side facing, make sure the part with the notch is facing toward the armhole. Pin and sew to join the shoulder seam. Repeat with the other Shoulder Strap. Fold the seam allowance of the strap and hem it from the loose end toward shoulder, along neckline and toward the other loose end. You have now finished the hemline for the shoulder strap and the neckline binding at the same time.

8. Place the loose end of the Shoulder Strap in between two notches on the Upper Back piece, right side facing (make sure it does not twist). Pin and sew. Repeat with the other Shoulder Strap.

9. Hem the Ruffle Trim using narrow rolled hem. Press to flatten.

10. Gather the Ruffle Trim and place it right side facing with the armhole created from the Upper Front and Shoulder Strap. Match the notches. Sew to join the Ruffle Trim to the armhole. Repeat with the other side.

11. Use bias tape to finish the remaining part of the front armhole.

12. Sew the hem of the blouse and any part that is still not finished.

Although there may be a lot of details to the Katty blouse, I believe it will worth the effort. This garment looks great on jeans and shorts and skirts, and it keeps you cool on hot summer days!
