The fit is very close. The lacing in the back gives some wiggle room so if in doubt, pick the smaller size. To be sure of the right size, crochet the first ch chain and put it around you, at approx. 2.5 cm (1 inch) upwards from your hip bone. The chain should not go all the way around but leave a 5 cm (2 inch) gap. The chain should not be stretched as you measure.

Cup sizes: A [B, C, D, E]

The cup size is chosen after the body is crocheted. This way you get a better and closer fit since we are all differently sized.

The cup size is calculated as follow = Full bust – under bust

A = 1 to 3 cm (0.5 to 1.25 inch)

B = 3.5 to 6 cm (1.5 to 2.25 inch)

C = 6 to 9 cm (2.25 to 3.5 inch)

D = 9 to 11 cm (3.5 to 4.25 inch)

E = 11 to 13.5 cm (4.25 inch to 5.5 inch)

The pattern is in American crochet.
