I used the Simplicity 1419 Liset pattern again. It is amazing what different looks you can get when you change small things.
To get the fake waistcoat effect I cut out two front bodices, and layered them on top of each other, cutting out the stripy one into a waistcoat shape. I left it loose over the waistband of the dress, only attaching the white underlayer to the skirt, so that it looks more like a waistcoat. I trimmed the edges of the waistcoat collar with white lace. I only used a single layer of striped material for the back.
