A woman's chest as measured around her breasts. The tailor took measurements of her bust to ensure the dress fit perfectly.
A period of economic difficulty or a sudden financial collapse. The dot-com bust of the early 2000s led to widespread layoffs.
A police raid or arrest, especially for drugs. The police conducted a bust on the illegal gambling operation last night.
