Hailey Baldwin was already showing off a lot when she attended the AMAs after party at The Nice Guy in West Hollywood on Sunday with pals Kylie Jenner and Tyga.

While wearing her sheer black lace mini dress, the 19-year-old model was flashing not just her decolletage but also her long, toned legs.

But when the Express spokesperson exited the venue, she also managed to flash her bottom and even the thin beige Spanx she wore under the dress.

At least she was wearing something: Though the catwalker had a brief wardrobe slip, she actually didn't show off too much. It could have been much worse

Though the catwalker had a brief wardrobe slip, she actually didn't show off too much. It could have been much worse. A decade ago, Britney Spears and Lindsay Lohan used to go out with no under garments on at all, to the shock of onlookers.

Baldwin also had on a pair of chunky heeled platform shoes in beige and brown that made her 5ft9in frame look even taller.

The stunner's blonde locks were pulled into a messy bun, and her neutral toned lipstick and black eyeliner made the Arizona native look even more comely. Thin but large gold hoop earrings added a dash of J-Lo.

Too bad the daughter of actor Stephen Baldwin looked a little stressed out as she navigated the crowd of fans waiting for her as she left.

Hailey Baldwin didn't attend the American Music Awards last night but she did join her friends at Justin Bieber's after party.

And while Gigi Hadid and Kylie Jenner both wore pieces by British label House of CB, Hailey showed off her impressive stems in a cute playsuit by Alexis. We love this lace look and it makes a great alternative to a little black dress.

The scalloped hem is super pretty while the neckline is plunging but doesn't reveal too much. If you're on the hunt for something to wear to your work Christmas party then how about trading in your dress for a romper?

The good news is, while it looks fabulous with bare legs, a pair of opaque black tights will look just as chic and you won't catch your death of cold. Always a bonus. Click (right) to buy Hailey's romper now at Revolve or get the look for less with one of the lace lovelies in our edit below.

For some reason the current New York resident had a band on her wedding finger. 

It is not known who she is dating at the moment, but over the summer she did spend a lot of time with singer Justin Bieber, who now appears to be back together with ex Selena Gomez.

Hailey was not alone at The Nice Guy.
