In this tutorial, I'll be showing you how to make a slip dress using my Celeste Cowl Neck Slip Dress sewing pattern. If you’ve been looking for a soft and elegant silhouette, nothing beats a silk slip dress. This pattern has a sexy cowl front with a sinuous line and best of all, it's all DIY slip dress.

Tools and materials:

  • Celeste Cowl Neck Slip Dress sewing pattern
  • 2 to 2.5 yards (1.8 or 2.5 meters) of silky fabric
  • Glasshead pins
  • Matching thread to the color of the fabric
  • Scissors
  • Sewing machine
  • Needle and thread (for basting)
  • Loop turning hook
  • Iron
  • Clapper for pressing (optional)


This dress calls for a silky fabric. You can use polyester silk, satin, or crepe.


You will need to iron the fabric multiple times during sewing to make the fabric be “obedient” while you sew. Pressing every seam gives a polished and professional look. It also helps to sew the series of stitches neatly.


You may want to use a clapper to help smooth and flatten the seams after every turn of the iron. To use a clapper, press your seam with a hot iron. When you lift the iron, place the clapper over the seam and hold it down until the fabric cools. Only move the fabric when it has cooled down.
