There is no single "ideal" chest size for a woman; beauty standards are subjective and vary across cultures and individual preferences.
While there isn't a universal ideal, clothing size charts often use chest measurements as a key factor. For example, a size medium, according to the Craft Yarn Council, corresponds to a chest measurement of 36-38 inches (91.5-96.5 cm). However, this is just a reference point for clothing and pattern making and does not define an "ideal."
Ultimately, the concept of an "ideal" chest size is a social construct, and individual perceptions of attractiveness are highly diverse. Factors such as personal taste, cultural background, and overall body proportions play a significant role.
