Of course, we’re talking about the Gossip Girl actress’s ultra-stylish best pal, Florence Welch (of Florence + The Machine), who sang three songs at Lively’s wedding reception on Sunday. The two ladies have quickly gained a reputation for being the most fashion-forward friends in Hollywood.
While we doubt the two are shopping in each other’s closets – Lively loves sexy minis and bombshell gowns while Welch tends to go vintage and quirky – one thing is for certain: They share a love of taking sartorial risks and a talent for pulling off over-the-top and unique ensembles.
After Lively’s nuptials in Mt. Pleasant, S.C., Welch was spotted leaving Wentworth Mansion, the luxury hotel where she was staying. “We had a lovely time. I only wish we could have stayed longer,” Welch, dressed in a short brown leather skirt, with a flowered chiffon top tucked in, was overheard saying.
Before the wedding, Welch was “very nervous,” Kacie Faulling, a hair and makeup artist based in Charleston, told PEOPLE. “Florence said [she was singing] for a good friend and this was her wedding gift for the bride and groom … She said she performs all the time, but she was performing at the wedding and she got nervous because it was for a friend.”
Welch was also spotted out sporting a throwback mustard-colored getup featuring loose drop-waist pants and a short-sleeve button-down top, cinched at the waist with a belt.
The bottom line: These BFFs (best fashion friends) aren’t ones to play it safe when it comes to fashion. And we’d love to see their personal styles rub off on each other. How fun would it be to see Welch go a little sexier once in a while and catch Lively in something ethereal and floaty?
