What I used: fabric, scissors, needle and thread, sewing machine and a button.
Usually, I try and copy the dress cut of a particular dress, but this time I decided upon doing things differently.
1. I cut the fabric into two parts (for the back and front). I bought 1.5 m so there were plenty leftovers.
2. I sewed the seam for all the parts, except for the lower ones (I left the decision about how long the dress would be at the end).
3. Then, I pinned the front and back parts to each other (make sure you pin the fabric with the inside towards you, like in the picture below). I wanted a cowl cleavage for the dress and hence the pinning below.
4. Afterwards, I put the dress on and used the pins to mark for the seams.
7. The dress.
