As one of the ultimate model moms, Heidi Klum loves to experiment with her wardrobe despite taking care of four children (and trudging through a divorce). Her latest go at sexy daywear is definitely one that's bound to raise a few eyebrows though.

The 39-year-old opted for a completely sheer top while walking through New York City yesterday with her children, Leni, Lou, Henry and Johan. The striped blouse featured an opening front and center held together with corseting detail -- not exactly your standard mom-gear. But the coup de grâce on the risky look had to be her completely visible black bra.

This isn't Heidi's first time at the bra-baring rodeo though, and the supermodel has been known to opt for see-through tops in broad daylight before. And if New York continues to be a humid sweltering pit of sweat, we're pretty sure we'll be seeing more of Heidi's bra in the next couple of weeks.

So what do you think of the "Project Runway" host's completely sheer, bra-revealing top? Do you think Heidi pulls it off or is it not quite mom-appropriate enough for you?
