I named this dress for all seasons because it can be easily adapted to any seasons.
For example: for autumn and winter you can do it as it is or you can make it simple withdout decrease to form the weist and withdout increase to form the hips.
For spring you can make it with a suitable yarn for this season and with a sleeve worked up to the elbow . In that case you need to make the decrease for the sleeves (like I will show you ) in every row .
For summer you can also work as it is but without sleeves . Also use a suitable yarn , and at the slevees you can make only the edge.
If you don`t want to make this dress you can make only a sweater. Yarn I use is Alize cotton gold . Is a soft yarn and it has 55% cotton and 45 % acrylic I use 5 skeins and a half, but depends for any szie. My model has S size. Crochet I use is 3 mm .
