Singer Geri Halliwell believes it is important for women of all body shapes to feel comfortable in a bikini, because she knows what it is like to be different sizes.

The 38-year-old beauty is known for her changing body shape, admits her experience with dieting and the female form helped her create her bikini range for Britain's high street brand Next, reports contactmusic.com.

"I have been all sorts of shapes and sizes to I know the importance of flattering shapes and styles," she said.

"For a great bust line, the contour at the top edge of a bikini has to be just right. And for those who need a little help, I have also designed some bikini tops with padding," she added.

For a woman to feel her sexiest, Halliwell believes leopard print is great for a "wow" factor.
