Used 67 grams for collar knitted with needle 4.5mm.
Only 4 underarm stitches for body instead of 8 and I omitted the hip increases.
Second skein longs for 8cm on body.
Knitted the sleeves before continuing on the body, used 103 grams per sleeve.
Used 12 grams for one pocket trim with needle 4.5mm.
Only 5 meters left, fortunately my 6 skeins had 120 grams each otherwise my yarn amount had not been sufficient.
