How it is made

A boxy block with a one-piece collar, two chest pockets and a straight hem. The armhole is dropped 3 cm so a jumper fits under without pulling.

Fit notes

This piece was tried on by 2 people whose measurements differ materially. Verdicts come from a fixed set of three, so a note can only describe how the garment sat, never the person wearing it.

Close means the garment sat against the body at that point. True to measure means it matched the flat measurement. Relaxed means it stood away from the body. Hem drop when seated and overhead reach are measured, not estimated.

Measurements

Garment measured flat and doubled where relevant, in centimetres, EU sizing. Every figure carries a tolerance of plus or minus 1 cm, because cloth is cut in stacks and no two pieces are identical.
