The 30-year-old reality star told Glamour magazine that she constantly worries about how she looks.
Kardashian, who has posed nude for Playboy magazine, confessed: 'I don't find myself as sexy as everyone thinks.
“I'm a lot more insecure than people would assume, but with stupid little things.'
She added: 'When I get dressed, I'm always so indecisive.
'It's a process. You have to learn to accept it. You have to learn to like what you see in the mirror.
'There are definitely times when I don't feel like myself, but you have to fake it until you make it.'
