Gavan/GettyMilla Jovovich's partially sheer dress showed a little more skin than she probably expected.
One of the biggest rules of red carpet fashion is making sure everything that needs to be covered stays that way.
Milla Jovovich seemed like she missed that lesson when she appeared at the Gorby 80 Gala Concert in London on Wednesday, in honor of Mikhail Gorbachev's 80th birthday.
The actress' dress barely kept her breasts hidden, leading the 35-year-old to pose for dozens of photos seemingly unaware that her right nipple was visible.
It seems Jovovich actually made a double-misstep in picking a dress that had a sheer top portion. Had the same design featured a solid fabric, her goods likely would've remained private no matter how she moved.

Regardless, don't expect to see the "Resident Evil" star in the questionable number again. She tweeted that the Valentino dress was just a loan.
"So sweet that they let me borrow it!" she wrote to a fan who said she looked "gorgeous."
And despite the wardrobe malfunction, Jovovich still thought it was "a beautiful night."
"It really turned into a monumental evening," she tweeted, adding that she "got all choked up" when making a speech on how Gorbachev helped Russian families like hers.
