2. Four reasons why women wear bras
1. Physiological support and health
The main function of a bra is to provide support, especially for women with larger breasts.

In a recent hot search, a fitness blogger sparked widespread discussion after sharing a case of "not wearing a bra during exercise causing sagging breasts."
2. Social norms and aesthetics
In cultural traditions, bras are considered part of “proper attire.” Social media data in the past 10 days shows that 70% of the disputes revolve around "whether it is appropriate to not wear a bra in public." For example, a certain actress was criticized by some netizens for not wearing a bra on the red carpet.
3. Psychological comfort and confidence
Some women believe that bras can improve their appearance and enhance their self-confidence. A recent survey by Xiaohongshu showed that 65% of respondents said “wearing a bra will make you feel more formal.”
4. Business drives and habits
The annual output value of the underwear industry exceeds 100 billion, and advertising and marketing have long shaped the concept that "wearing a bra = a must-have for women". Taobao data shows that sales of new products such as "seamless bras" and "sleeping bras" have increased by 40% in the past week.
3. The main arguments against wearing a bra

| "Health hazard" | 30% | "Underwire compression of lymph nodes causes breast cancer?" |
| "Gender equality" | 25% | "Why don't men wear them?" |
4. Different voices of experts and netizens
Medical community:A breast doctor from Peking Union Medical College Hospital recently pointed out on Zhihu that bras are not necessary, but they need to be chosen according to individual needs and avoid styles that are too tight or have underwires.
Feminist:The Weibo topic #NoBraDay sparked heated discussions, with some users believing that "whether to wear something or not is a matter of personal freedom and there is no need to be judged."
Ordinary consumers:A Douyin poll showed that 60% of women chose "depending on the occasion" and only 15% insisted on "absolutely not wearing it."
5. Conclusion: Personal Choice and Social Inclusion
There is no standard answer to whether to wear a bra or not. The key is to respect individual differences. As social attitudes progress, more and more women are making choices based on comfort rather than traditional norms. In the future, this topic may continue to trigger in-depth discussions about body autonomy and cultural habits.
