In a manual to be published later this year, women and girls are instructed on what to wear at home, at work, at the theater, and during various celebrations.
Among other things, Tajik women are advised not to wear "revealing" Western clothes or Muslim headscarves.
The advice has sparked outrage in the former Soviet state in Central Asia, which has been ruled with an iron fist by President Emomali Rahmon since 1992.
There are so many economic and social problems – power shortages, air quality, migration to Russia, says pharmacist Firuza Naimova in the capital Dushanbe.
Why do they want to give women lessons? We can choose our own clothes.
In an earlier manual from 2018, the government advised women to avoid "European" clothes, including mini-skirts and low-cut tops, as well as black clothes and hijabs.
Those who wear foreign clothes, such as hijabs, think they are different. But they are nothing. They trample on our values and undermine our identity, the president has previously said.
There are no corresponding state dress codes for Tajik men. Beards, however, are banned, and anyone with facial hair risks being seen as suspected Islamist extremists.
