Heidi Klum loves to see ''more cleavage and less bra'' when she wears underwear.

The 47-year-old supermodel - who collaborated with lingerie company Bendon to launch her debut underwear line Heidi Klum Intimates - has admitted her creative ideas for her collection were ''limited'' at first, although the shape of her new bras have been designed to not conceal a woman's chest.

Speaking about her eponymous collection, the blonde beauty said: ''I'm not just slapping my name on things. I have an opinion and I am designing.

''In the first year I was limited with what I could change, but now the customer is starting to see a lot more of my own creations. I personally like to see more cleavage and less bra so I adopted a more natural shape.''

However the mother of four - who has daughters Helene, 12, Lou, six, and sons Henry, 10, and Johan, nine - was able to experiment more with the swimwear capsule.

She explained: ''They [Bendon] wanted to do swim. It was a natural transition and it was fun to do because I could completely start from scratch. I wanted to put my own stamp on it.

''The beach demands a different sort of confidence than lingerie does because people are seeing you in public. The fit is so important and it's crucial to have a range of shapes and styles so that you can mix and match for your body shape.

''I hope all women wear and feel comfortable in my pieces. I like to think that there's something for everyone.''

Although the 'Project Runway' judge has confessed designing beachwear was the ''hardest'' thing for her because she prefers to wear two piece bikini sets, rather than an all in one swimming costume.

Speaking to Luxury London online she said: ''Designing the bathing suits was the hardest part for me because I don't really wear them; I wanted to make one-pieces that are cool and sexy, but also functional. And with the prints I tried to make them fun, but elegant at the same time.''
