Beyonce’s Mom Says Daughter’s Style Has Always Been ‘Edgy’

'It's just a result of her constantly evolving,' Tina Knowles says of the fashion in Beyonce's "I Am ... World Tour" DVD concert special.

Beyoncé has never been shy about hitting the stage in stunning costumes. Her appearance has always been a mixture of showgirl sparkle and pop star razzle-dazzle. And her style is on full display in her new DVD concert special, “I Am … World Tour.”

Her mom and stylist, Tina Knowles, said that while the looks may seem a bit edgier than what fans have seen from the singer in the past, she thinks that her superstar daughter has always been ahead of the style curve.

“Well, the wonderful Thierry Mugler designed the costumes, and I actually worked on some of the dancers and the band, and it was just amazing to work with him because he is so creative,” Knowles told MTV News at a New York screening of the special. “So it’s just a result of her constantly evolving, but she’s been edgy. It’s funny for people to say she went more edgy, but she’s been wearing body suits and that type of thing.”

And while Knowles may act as her daughter’s stylist and costume designer, she says that Bey’s style decisions are all her own. “Well, we discussed her working with Thierry Mugler, and I’m the biggest fan. And so she had seen some of the fashions and she loved it,” she said. “So we always discuss things, but it’s her decision, it’s her career.”

Beyoncé, who also directed the concert special , said it gave her a better understanding of the filmmaking process. “It was hard work,” she said. “I learned so much. I have a new respect for directors and I think I would like to do more of it. … Well, I’ve done some co-directing for music videos [but] this was definitely a big step for me, and I’m so thrilled.”
