https://www.bbc.com/news/world-asia-china-66737272A draft law banning speech and dressing "detrimental to the spirit of Chinese people" has sparked debate in China.
If the law comes into force, people found guilty could be fined or jailed but the proposal does not yet spell out what constitutes a violation.
Social media users and legal experts have called for more clarity to avoid excessive enforcement.
China recently released a swathe of proposed changes to its public security laws - the first reforms in decades.
The clothing law has drawn immediate reaction from the public - with many online criticising it as excessive and absurd.
The contentious clauses suggest that people who wear or force others to wear clothing and symbols that "undermine the spirit or hurt the feelings of the Chinese nation" could be detained for up to 15 days and fined up to 5,000 yuan ($680; £550).
Those who create or disseminate articles or speech that do so could also face the same punishment.
The proposed legal changes also forbid "insulting, slandering or otherwise infringing upon the names of local heroes and martyrs" as well as vandalism of their memorial statues.
