The singer's stylist, Johnny Wujek, said that the 26-year-old will not be dumbing down her dress sense now that she is married to Russell Brand.
He told Contact Music, 'It's fun to be all over the place, glamorous one minute, and silly the next. There won't be a radical style change, just an evolution. She'll always be her quirky self.
'Neon is big for spring so I'll be getting her into a few pieces, but generally Katy wears what she wants, it's never dictated by trends.
'One thing's for sure - she won't be dressing more conservatively now she's married to Russell, no way, never! She calls the shots when it comes to hair and makeup, and always has a vision. She's into so many different looks. She had her heart set on the blue wig she wore to the last MTV Movie Awards.'
