As this is a Measure & Make design, I cannot predict how much yarn you will need. The sample was made for a bust measurement of 105 cm and 700 g yarn was used.
Do not use any yarn thicker than fingering weight as the tee will probably be too thick and too heavy, and you will use a lot of yarn.
Choose a hook suitable to the yarn you are going to use. Swatch and make sure your tension is to your preference.
