The 42-year-old supermodel has just released her latest collection for her lingerie brand Heidi Klum Intimates and she has revealed she doesn't just save her raunchiest sets to wear at home for her boyfriend, New York art dealer Vito Schnabel.

Heidi likes to go out in matching lingerie, including stockings and suspenders, to give her man a glimpse of what's to come later.

In an interview with News Corp Australia, she said: "When I go out to dinner, I wear garter belts and I wear stockings ... under a short little dress and then when you sit down, you see it on the side a little bit, just a little bit. I don't think you should get anything that will only live in your drawer and never see the light of day. You have to feel confident enough to pull it out and wear it otherwise what's the point? When you sit and cross your legs, you see just a little bit.

Heidi - who was previously married to Seal and raises four kids with the British singer - has also shared her top tip for buying underwear.

The German model-and-designer insists when purchasing a matching lingerie set always buy three pairs of panties to one bra.

She said: "I always wear matching bra and knickers and a tip of mine would be to get three bottoms to one bra, so you can wear the bra a few days and always have the matching panties to go with it. I feel like they always kind of get lost too, like socks."
