Construction:
This is a floating slightly A shape Tee made bottom up in one piece in the round up to the arm holes. Then it is knit flat with with shaped shoulders and a square neck hole. The hem starts with a garter stitch band. The intriguing pattern is created through stripes which are spaced differently going up and waves created through increases and decreases. The shaping results just from the stripy wavy pattern. The neck band and the arm finish with a small rolled band. The top should have not more than 5 cm ease around your bust. The sizes are just a change of the number of stitches in the pattern repeat.

The measurements are on the schemata in the photos
