Cleavage enhancement is a term used to describe the process of making a person's bust look larger and more prominent. There are several synonyms for this term which include cleavage boosting, bust enlargement, breast augmentation, and chest amplification. Cleavage boosting refers to any clothing or accessory that accentuates the cleavage, such as push-up bras or deep V-neck tops. Breast enlargement or augmentation, on the other hand, is a medical procedure that involves the use of implants to increase the size of the breasts. Chest amplification is a term that can be used for both men and women and involves using clothing or padding to create the illusion of a larger chest.
