Mary-Kate And Ashley Olsen Stun At Friend's Wedding In South Of France

If you're a "fashion person," there's no doubt you have or have had an obsession with the Olsen twins and their signature styles. And if you're not a "fashion person," you're at least somewhat fascinated by the 30-year-old sisters who made their acting debuts in "Full House."

Either way, you know that photos and public appearances by the twins are rare (they only just posted their first-ever public selfie this past April) and are considered a novelty of sorts.

So world, brace yourselves, because we have new photos of Mary-Kate and Ashley ... and they're good.

The actresses-turned-fashion designers attended a very fancy wedding in the south of France over the weekend and you can bet they brought their style game to the occasion.

To celebrate the nuptials of collector Alberto Mugrabi, 46, and Minnie Muse fashion blogger Colby Jordan, 23, the twins went all-out in their wedding guest attire, with Mary-Kate donning an off-the-shoulder black dress with white lapis detailing and a diamond necklace and Ashley in a dark green and black gown adorned with embellishments.

Both the girls styled their hair in chic updos, a refreshing change from their usual flowy, bohemian locks.

And they weren't the only ones from the fashion crowd in attendance — models Heidi Klum and Karlie Kloss were among the 600 special guests, celebrating alongside Owen Wilson, Sienna Miller, Poppy Delevingne and Princess Beatrice.
