Producing, importing and selling synthetic lace panties will be banned this summer within the Customs Union, a trading alliance between the three nations, the Moscow Times reports. The law was passed and took effect in 2012, but won't be strictly enforced until July 1.
The trade bloc says that synthetic lace does not absorb enough moisture.
The ban has outraged some women, and sparked a demonstration in Almaty, Kazakhstan. Protesters wore lace underwear on their heads, and three women were arrested for trying to put panties on a city monument.
