While preferences vary significantly, research suggests that men tend to find C and D cup sizes most attractive. This finding is based on a study examining sociosexuality and preferences to women's breasts, where men with a short-term mating orientation rated women with larger breast sizes, most notably C and D cup sizes, as more attractive.
However, it's important to note that this is just one study, and many other factors contribute to attraction, including personal preferences, body shape, and overall confidence. Additionally, some men might prefer smaller breast sizes, while others prefer larger sizes, and some might not care about size at all.
Ultimately, it's crucial to remember that beauty is subjective, and there is no single "perfect" bra size that will universally appeal to all men.
