What is Chyler/Alex wearing?

Oh wow! I wonder if this is related to that photo that someone posted earlier discussing her getting a possible suit?

Do the World Killers have that \ / outline on their chest? I hope that she isn't a World Killer. That would be too similar of a set-up as Season 1 when she and Kara went against each other because of Myriad. It would be cool though if she got a Legion ring and doubly awesome if that blank outline is supposed to represent the House of El considering she is Kara's sister.

On a completely superficial, non-related and non-important side-note, I do not like Chyler's hair that color at all. I wish she would color it so it was more brown with red highlights rather than the mahogany that it is now.

The \ / looks blank to me, like Mon-El’s current jacket and pictures of his red suit. Maybe Alex gets a Legion ring. It would make sense for Alex to have a blank \ / because she’s related to the house of El but not Kryptonian.

Here's a second look. The suit has the \S/ outline which now makes me think Alex could be infected by the Worldkillers or something.
