My observations from the trailer:
1. In the shot of Ken, Asha, Emily, Valerie and Alexander you can see that there is another couch at the right with more designers. In the next shot wee see that Dom is one of them. We see at least 3 more designers in the couch. These could look like Layana, Mitchell and Sam. Alyssa tells this is a naked runway.
2. As already pointed out here, there are (several) shots of Kini, Layana, Asha, Dom, Ken, Sam, Emily at the MCU Park Stadium, so they must be Top 7.
3. There is an unconventional material challenge at a fire station. Here we see Layana, Asha, Kini, Ken, Emily, Mitchell, Alexander, Valerie, Dom, Sam and Stella. This means that Daniel should be next out.
4. We also see the following shots:
Parade: Dom, Sam, Emily Valerie is annoying: Stella, Valerie, Kini Layana crying: Layana, Asha, Ken, Alexander Black/white patterns: Dom, Sam
So if all of my speculations are correct, we have:
2nd out: Daniel
Firestation (Top 11): Layana, Asha, Kini, Ken, Emily, Mitchell, Alexander, Valerie, Dom, Sam, Stella
3rd out: Stella Naked runway (Top 10): Ken, Asha, Emily, Valerie, Alexander, Dom, Layana?, Mitchell?, Sam?, (Kini)
4th-6th out: Mitchell, Valerie, Alexander MCU Park Stadium (Top 7): Kini, Layana, Asha, Dom, Ken, Sam, Emily
