The flowy leafy vest is made top-down and there is no seaming.
In the pattern there are written instructions (US terms) and charts. You can crochet the vest without using the charts, but they can be a great help when in doubt.
There are 8 different sizes. In size 1, 2, 3 and 4 there is only little difference between the width of the back and the front. In the larger sizes there is more room in the front. Furthermore you can add rows to the edge and get even more room in the front.
The vest has A-line shape. There are 2 options in the pattern for regular width and extra width. The shown vest is size 4 made in regular width.
