Blake Lively accidentally wore her Versace underwear inside out during It Ends With Us tour

Blake Lively has suffered a hilarious underwear mishap while promoting her new movie in New York City.

Blake Lively, you are an outfit repeater!

While the Gossip Girl star, 36, has no doubt been on a fashion roll over the past few weeks, stepping out in a variety of floral-themed looks, she opted to re-wear an old ensemble in New York City on Monday — and had a good reason for doing so.

“I wore this yesterday,” she admitted as per Page Six while speaking to fans and photographers, who captured her rocking the same see-through beaded top, embellished jeans and branded briefs, which peeked out from the top of her pants.

“But I wore my underwear inside-out,” she explained. “So I wore it wrong and I can’t do that to Versace.”

According to Lively, the pink and denim outfit needed a “round two” because when styled inside-out, the band on her briefs appeared black rather than the co-ordinating light pink colour.

“It’s disrespectful,” she noted, adding that she was “in a hurry” when she initially wore the look on Sunday.

And her Versace streak didn’t stop there; At the premiere for It Ends With Us on Tuesday, the Blake Brown haircare founder turned heads in an archival piece from the fashion house that was once worn by Britney Spears in 2002.

“It is Britney’s actual dress,” she told revealed to People, sharing her excitement over the sparkly, multi-coloured design. “It should be in the Smithsonian [Institution] or the Met[ropolitan Museum of Art], but it’s on me.”

Lively fangirled some more on her Instagram Story, sharing a photo of Spears wearing the floral dress alongside text that read “Todays mood.”

“Britney, us millennials all have a story of a moment, or of years that you made us want to shine and inspire awe, with strength, and joy and immensely hard work,” she wrote in the post.

While It Ends With Us officially premiered on August 8, it doesn’t appear that the mum of four is slowing down when it comes to cool outfits, all of which pay tribute to her character, florist Lily Bloom.

On Thursday, she promoted the highly-anticipated film in London while wearing a white, floral embroidered Stella McCartney suit, which she styled without a top.

We’re loving this flower power era, Blake!
