Russia and two of its ex-Soviet neighbours are set to impose a ban on certain types of lace panties, sparking public fury and even a lingerie-themed street protest.
Coming under a complete ban this summer in Russia, Kazakhstan and Belarus are lace or net knickers that have a high synthetic content, due to a new hygiene rule.
The rule is set to come into force in the Russia-led customs union of the three countries and has prompted plenty of amusement and newspaper photographs of women's bottoms, but also fears over a return to Soviet-style regulation of everyday life.
"Lacy panties are heterosexual propaganda to adults," wrote Moskovsky Komsomolets daily, referring to a recent Russian law banning so-called gay propaganda to minors.
"Bureaucrats are poking into women's knickers," complained Express Gazeta tabloid.
"What? I'm emigrating," Russian pop star Viktoria Daineko wrote on Twitter. Other bloggers mockingly posted pictures of shapeless knee-length undergarments. "Coming soon to all girls in the country," one said.
Underwear retailers raised concerns that much of their sexier lingerie will fall under the ban, while other observers saw a return to Soviet-style arbitrary rules and lack of choice.
In Kazakhstan's former capital of Almaty, three women protested by putting lacy knickers on their heads and attempted to lay them at an independence monument last weekend.
"They have robbed the people so much that we can only give away the last thing we have," said one of the protesters, Zhanna Baitelova, a journalist at Assandi Times newspaper.
"Now they're even deciding what kind of underwear we should put on," she told AFP.
The protesters - two journalists and an art critic - were promptly arrested, found guilty of petty hooliganism and ordered to pay fines of around $US100 ($A111).
