Only the smallest size had been knitted (the one on the photos) yet.
The person who models the vest is between EU 36 / USA 4 / UK 8 and EU 38 / USA 6 / UK 10 sizes regarding the parameters given for this sizes in a table included in the pattern. If you are between sizes and would like a vest that covers your abdomen opt for the bigger size.
In case you don’t like the sateen ribbon belts, just ignore the instructions for making holes for the belt.
In case you would like the vest to cover more of the chest area, you can simply add more stitches to the front (that would increase the yardage too).
If you find any mistakes, please notify me so that I can correct the pattern.
Enjoy knitting and wearing this vest!
