Burmese activist Chaw Sandi Tun has been jailed for six months for mocking the country's army on Facebook.
She was found guilty of insulting the army chief by suggesting he wrap Aung San Suu Kyi's sarong round his head.
This followed humorous exchanges by internet users who noticed the colour of the army's new uniform matched some of the pro-democracy leader's clothing.
Critics say the conviction is part of a wider crackdown on protest and free speech in Myanmar, also called Burma.
The Facebook post in question was written in October after the army unveiled its new uniform as part of a rebranding exercise.
The army's commander-in-chief Min Aung Hlaing - who BBC correspondents say is a prolific Facebook user - modelled the new uniform online. The light green colour matched a sarong previously worn by Ms Suu Kyi.
This set off a series of internet memes, with composite pictures made to suggest the army chief was mimicking Ms Suu Kyi's sartorial taste.
The court in Ayeyawady Region found that Ms Chaw, 25, an activist for Ms Suu Kyi's National League for Democracy (NLD), shared the picture and added her own comment, saying: "If you love Mother Suu so much, why don't you wrap her sarong around your head?"
