The 43-year-old singer, who has five-year-old son Ethan with her ex-partner Kris Smith, said she struggled to find clothes that would fit her "weird" shape, reported Contactmusic.
"I always thought there was something wrong with me. I was constantly thinking, 'I'm a really weird shape. Nothing fits me. How do other people just take something off the rack and put it on?'," she said.
Dannii, the younger sister of pop princess Kylie Minogue, learnt to love her body over the years but she's also launched her own clothing line 'Dannii Minogue Petites' to help other people dress their curves.
