One question stumps stars and designers on the CFDA Awards red carpet

When designers and stars made it to our corner of the world on the 2017 CFDA Awards red (read: pink and blue) carpet on Monday night, we had one fun question to ask them -- but we didn't realize it would stump so many of them.

See all the red carpet looks:

"What's one fashion 'rule' that you love to break?" Seems simple enough, right? You know: no white after Labor Day, don't mix navy and black, be wary of denim on denim. However, aside from 15-year-old Rowan Blanchard (she wears socks with sandals, and we love her for it), we didn't really get responses like that. One common belief we gleaned, though? Whatever the rules are (if there are any at all), they're meant to be broken.

See how stars like Heidi Klum, Bernadette Peters and Bella Hadid answered the question:

"Oh, I love to break all rules!"

Cecile Richards

"I don't know! I don't know if it's a rule, but my mom would never wear high heels, [but] I love to wear them. I mean, I'm already too tall as it is ..."

Getty

Heidi Klum and Zac Posen

Zac: "She loves breaking all the fashion rules! If there's a rule, it intrigues her to break it. There's really no such thing as rules. Rules are meant to be broken."

Heidi: "Well, right now, everyone's okay with that. 10 years ago, it was not okay. Now, everything that doesn't work works, right? Clashing of different prints. A few years ago, the prints had to clash the right way. Now, the uglier the better!"

Getty

Bernadette Peters

"Are there many rules anymore? I think they've all been broken. You know, I think diamonds and rust is always great."

Getty

Sander Lak and Brit Marling

Sander Lak: "That's a really hard question. I don't really know what fashion rules are, to be honest. I think I've been doing this for too long to really understand there are rules. I just do what I want."

Brit Marling: "I'm not sure I know what the rules are either. I don't keep up enough with the trends. I wear white year-round, I wear black where I'm not supposed to, I wear color to funerals."

Getty

Rowan Blanchard

"Socks with sandals -- it's just fun and comfortable."

Getty

Brooke Shields

"Dressing the way other people tell you you have to."

Getty

Bella Hadid

"I don't know, I like to break a lot of rules. I'm not sure there's one exactly."
