In this tutorial, I’m going to show you how to make a DIY slip dress with side slits. Sewing a slip dress is not a complicated project, and even beginners can achieve this.


Besides that, you can wear this gorgeous dress during all seasons, with a bit of layering where needed. Let’s get the show on the road!

Tools and materials:

  • 1.8m linen fabric (2 yards)
  • Sewing machine
  • Pins
  • Matching thread
  • Paper
  • Ruler
  • Chalk
  • Pencil or marker
  • Measuring tape
Measuring the length of the slip dress on paper


Measuring the length of the slip dress

1. Make the front DIY slip dress pattern

Measure from just above your bust to over your knee for the length of the dress. Mine was 110cm (43.30”). 

Marking the width of the chest


Measuring the width of the chest

At one end of the horizontal line, draw a 13cm (5.11”) vertical line on either side. This is the width of your chest, in between your shoulders + 2cm (0.78”). My measurement was 26cm (10.23”). 

Marking the bust area


Measuring the bust area

From one point of the vertical line, measure 18cm (17.08”) and mark accordingly. This is the area from above to over your bust. Also, add 1cm (0.39”) for seam allowance.

Then, draw a 22cm (8.66”) line on either side (from the cutting point of the 18cm [7.08”] lines). The measurement should be half of your bust size + 3cm (1.18”) for seam allowance.

Measuring from the bust to the hips

Next, measure from just above your bust to the middle of your backside. Mine measured 50cm (19.68"), and I drew this from the first straight line.

Measuring the hip area

From that cutting point, draw another straight line measuring half of your hip size + 6cm (2.36”) from that cutting point. Mine was 52cm (20.47”) (26cm on each side).


Tip: If you want a loose fit, you can make this part bigger.

Then, connect the marks from the second straight line to the third line.

Draw a straight line at the end of the horizontal line. This measurement is based on half of your hip size + 20cm (7.87”). I measured 33cm (12.99”) from the cutting point, so I had 66cm (25.96”) total.

4. Make the facing pattern

From the second straight line, measure 12cm (4.72") on each side and draw a line across. This part will be for the inside front pattern (the facing). 

Back inside facing pattern

The part between the second and third lines will be the inside pattern for the back piece (back facing). 

How to make a pocket pattern

5. Make the pockets

Cut a rectangle measuring 30cm x 20cm (11.81x7.87”). 

Drawing the curve of the pocket

Cutting out the fabric pattern pieces

6. Cut the fabric

Cut out the patterns in your linen fabric. Remember, you’ll need four pieces for the pockets. 

How to sew the pockets

7. Sew the pockets

In order to know where to place the pockets, simply mark where the second part of your front pattern is located; the pockets should be placed there. 

Pinning the pockets to the slip dress

Pin the pockets, right sides facing, and sew. 

Pinning the pockets to the back of the slip dress

Do the same for the back part of the dress. 

Pinning the front to the back pattern

Lay the back piece onto the front, right sides facing. Then, pin the sides and pockets. 

Marking slits in the DIY slip dress

However, I want to have slits on my dress, so mark around 35cm (13.78") from the end of the dress and pin up until that point. 

Sewing the pinned sides of the dress

Now, sew the pinned sides. Be sure to pivot by the pockets. 

Sewing the pockets into the slip dress

Mark 14cm (5.51”) from the top of the pocket and sew downward. This is the open area of the pocket. 

Hemming the DIY slip dress and slits

8. Hem

Hem the slit areas by folding the fabric twice. Also, do the same for the bottom of the DIY slip dress. 

Sewing the facing

9. Sew the inside parts

Connect the inside part of the front and back, on the sides. 

Pinning the facing inside the dress

Put this piece inside the dress and pin in place, but don't sew yet. 

Measuring straps for the DIY slip dress

10. Make the straps

Cut two rectangles measuring 40cm (15.74”) long and 6cm (2.36”) wide. I got this measurement by measuring my shoulders (add 2cm [0.78”] seam allowance). 

Pinning the straps ready to sew

Fold each strip in half and sew along the edge. Sew and turn right sides out. Then give it a good press. 

Pinning the straps to the dress

Place each strap 10cm (3.93”) from the edge of the back part. 

Attaching the straps to the dress

Place the strap inside, between the dress and the facing. 

Sewing the top of the slip dress

Sew all layers together. 

Understitching around the edge of the facing

Then understitch around the facing’s edge.
