A moment of triumph nearly turned embarrassing for Russian speedskater Olga Graf.
The 30-year-old gave the home country a reason to cheer on Sunday (local time), winning Russia's first medal when she took a surprising bronze in the women's 3000 metres.
She even got a note of praise from Russian President Vladimir Putin.
When Graf's time flashed on the scoreboard - 4 minutes, 3.47 seconds was a personal best - the crowd at Adler Arena erupted in cheers. She whooped it up on her warm-down lap, then unzipped her skin-tight suit right down to the belly button.
She was wearing nothing underneath.
"I totally forgot," Graf said sheepishly through a translator. "We have very good suits and they are very tight. ... You just want to breathe and you want to take off your suit."
When she realised her faux pas, Graf quickly zipped the suit back up with a mortified smile.
"Only afterward," she said, "did I realise that maybe this video will appear on YouTube. But I don't think it will be so bad."
