Bella Hadid and her sister, Gigi, may be ruling the runways, but they're making the real fashion statements on the street.

While in Italy for Milan Fashion Week on Thursday, the 19-year-old model rocked one of the tiniest black tube tops we've ever seen. From the distressed Canadian tuxedo to the thick denim choker she paired with it, this look screamed '90s, right down to showing off her rock hard abs.

The ensemble is right in line with Bella's signature style, as she's a big fan of belly-baring crop tops, sheer shirts, or, well, nothing covering her chest at all.

She and Gigi were both crazy busy on Thursday, walking in shows for Max Mara, Alberta Ferretti, Moschino, and Fendi, with Bella opening the latter.

In fact, the tube top made an appearance in an Instagram video Bella took with Gigi backstage at Moschino.

The ladies looked quite retro at the show. Both wore wigs and bold throwback dresses and, well, a couple other interesting looks to look like paper dolls. Beach bod dress, anyone?

Even the Hadids' fellow models are fully aware of how hard the sisters work. Coco Rocha praised them in a sweet tweet, writing, "I've been doing this modeling thing for a minute and I want to say, for the record, @GiGiHadid & @BellaHadid are the REAL DEAL. #supermodels."

The ladies quickly voiced their appreciation. "@cocorocha thank you so much for your warmth and support always COCO! Means a lot," Gigi wrote, adding three heart emojis, while Bella responded, "@cocorocha @GiGiHadid coco!!!! Thank you! Means so much coming from u."

Bella was wearing that ab-tastic outfit when Gigi got accosted by a fan who was supposedly "pranking" her by lifting her up in the air out of nowhere. Find out more about the creepy incident -- and how the 21-year-model defended herself -- in the video below.
