Yes it is piece 4, no you haven't missed 2 & 3... I am just sewing the pieces in an order that suits the current warm autumn weather we are having. My second piece is a boiled wool coat and it is too warm to be handling wool. In fact my top was intended to be a merino jersey top but I decided a 3/4 sleeve top in rayon would actually got worn more quickly.
I used New Look 6150 again. I previously made it here. Sadly the last top is much loved but the fabric is pilling and deteriorating at a fast rate. When I made the blue version, I did actually buy some rayon knit for a second version, so decided that now was the time to make it up.
This pattern fits me well with no alteration. I chose my size based on my bust size +1" ease and chose the size that corresponded with that as marked on the front bodice pattern pieces. The pleats and gathers are a bit fiddly but the rayon takes pressing well and the fiddle is well worth the effort of the finished top.
I really need to make more of this pattern and will try the boat neck (View D) next time.
Ciao kittens ... pants next (piece 3)... holding my breath to see if I can make the deadline of all 4 pieces but still holding onto some hope...
