The best way to promote your own underwear collection? Pose in it for the world to see, a la Heidi Klum.

The 42-year-old model stripped down to a tiny lacy thong from her Heidi Klum Intimates range, flaunting her toned and taut butt for her Instagram fans to see.

“I love being cheeky,” she captioned the pic.

Paired with wet, slicked back hair, smoky eye make-up and dark nail polish, the black and white snapshot oozed sensuality and seductiveness – much to the joy of her 2.3 million followers.

“I wanna write a book about that booty,” wrote one happy fan.

But some of the model’s followers would love to see her create underwear for women with bigger bust sizes.

“Can you please make some adorable bras and panties sets for young women like myself at 22 with a 32 H size chest. Because though hard to come by I really hate the bras in my size :( I don’t want to wear a bra made for someone In their late 30s and 40s (sic),” commented on Insta user.

Other people commented on the Klum’s slim frame, expressing concern that she’s too “skinny”.

Of course, Klum is completely used to stripping off for the camera. The mum-of-four’s Instagram profile is bursting with snaps of her posing in underwear from the Bendon-made line. It was rebranded last year, transforming from Elle McPherson Intimates into Heidi Klum Intimates.

While the range is a little pricey, the German model has a more affordable line called Heidi by Heidi Klum.

Klum puts her wow-factor figure down to a combination of working out regularly and eating healthily. She’s spoken before about doing cardio workouts and circuit training with celebrity trainer David Kirsch to shed her post-pregnancy weight and is a big fan of snacking on almonds, instead of sugary treats.

“Raw almonds are the perfect snack. A handful can hold me over to my next meal. Best yet, they are so good for you,” she told Shape magazine.
