Marshmallow is a trapeze ruffle dress with a bottom ruffle, 3 collar options to sew: Peter Pan, a bow and bias binding, and 3 sleeve lengths.

This sewing pattern is perfect for beginners and confident makers alike and also features a long back button placket and inseam pockets.

Depending on the fabric you go for you can make it and wear it all year around.



The lovely Marshmallow trapeze ruffle dress sewing pattern comes with three different sleeve options: 3/4 sleeves and cuffs, short sleeves or sleeveless. It features a loose, comfy fit and a fun ruffle, Peter Pan collar and optional cute bow.

The dress can be dressed up or down, from a Christmas party to a wedding, from a walk around town to the office with a belt for a close fitted look.

And if you like this version for adults, you can also make a Mini Marshmallow trapeze ruffle dress sewing pattern for little girls age 3 to 12.

You can also learn how to sew and make this ruffle dress sewing pattern on our YouTube Channel.

This is the perfect trapeze ruffle dress pattern for a beginner or confident beginner.

Suggested fabrics and requirements

For Autumn and Winter choose medium-weight wovens like cotton, cotton blends, light to medium wools, denim, corduroy or flannel.

Meanwhile, during Spring and Summer opt for light to medium-weight wovens similarly to medium cottons, linen, chambray, lighter denims, double crepe and crepe.


Version A – 3/4, short sleeves – 115cm/45’’ fabric: 2.7m/2.95 yd*
Version A – 3/4, short sleeves – 150cm/60’’ fabric width: 3m/3.28 yd
Option B – sleeveless – 115cm/45’’ fabric width: 2.5m/2.73 yd*
Option B – sleeveless –150cm/60’’ fabric width: 2.3m/2.5 yd

*This alternative is only valid for all the dress pieces minus the ruffle as this piece is wider than the fabric. Therefore, you will have to choose a 150cm-60’’ wide fabric just for this piece with an approx. 40cm length. To sum up, this option is great for making a contrasting version like the one on the cover with a different fabric for the ruffle.
