bustline 
noun
The measurement round a woman’s body at the bust: these figure-enhancing bras will immediately increase your bustline...
- If you were to look in a mirror and see a bone structure enhanced by cheekbone implants or a bustline pert with silicone, would the so-called improvements bring an enhanced sense of satisfaction with the self?
- If your bust measurement is a full size larger or smaller than the pattern, blend the adjustment line from the waistline to the bustline of the next size.
- Accent bustline with a deep neckline or off-the-shoulder bodice.
