Let’s draft together the pattern of this sexy evening dress.
Get a stretch fabric and the pattern of a basic dress with bust dart.
Manipulate the bust dart to into a french dart.
Draw the front and back neckline and change the skirt into a mermaid style (reduce at the knee, flare at the hem).
Reduce 1-2cm at the back waist to have a more fitted skirt.
Trace the separate pieces and draw a strip for shoulder straps and back fastening.
