Project Runway’s fashion expert Tim Gunn had some harsh words to say about the fashion sense of some of Hollywood’s best known starlets, OK Magazine reported.

In an interview with OK, Gunn complained that “Hannah Montana” tween star Miley Cyrus was “just a little too tarty.”

“I don’t want her to look like she’s going into a convent school, but it’s just a little too much for a 15-year-old,” he told OK. “If I didn’t know better, I’d swear she was 25!”

But Cyrus wasn’t the only starlet to which Gunn, who also hosts “Tim Gunn’s Guide to Style” on Bravo, offered his advice. He also cautioned Katie Holmes, who he claims has the opposite problem of Cyrus.

“She went from looking like a little farm girl to looking like European royalty,” he raved to OK. “Now she needs to push back a little so that she doesn’t look too dowdy or old.”
