How to Draft a perfect Breast Cup with Chest tightening

Take your breast cup measurements from breast side to the middle and from under bust to desired chest covering(chest line) mine is 7.5inches both ways.
put your measurements down and square it out as seen on the video...Mark your chest line, bust point and Under bust line
At your bust point line impute your Nipple to Nipple measurements but be sure to take out your mid breast space before inputting the figure and Mark straight line up down(1,1.5 or 2 inches depending on the individual mid space)
Take out half, 0.75, 1 inch or more on both side at your under bust(UB) line depending on your bust size...mine is 36 so I took out 0.75 both side; same with the Side bust(SB)
Depending on the bust size Take out half inch or 0.75 at the chest line for tightening. Also at the Center bust (CB) take out half an inch on both sides.
At the Bust point mark 1 inches round and from there connect it to the tightenings you've marked out, At the SB upper side go in by half an inch and curve to the Chest Line
At the mid breast space; go up by 2 or 2.5 inches and curve up to the chest line
Curve the under bust as seen on the video.
Trace out pattern, place on Fabric and cut out to sew.
