Supergirl may be Categoriesfrom Krypton, but she can totally pull off the Themyscirian look.

In this 45-second promo for Wonder Woman -- a 30-second version of which played Monday night during the CW's broadcast of Supergirl-- we get a little glimpse of what Kara Zor-El (Melissa Benoist)might look like standing in Diana Prince's soon-to-be-iconic battle footwear.

Speaking of Diana Prince, she's in this too -- as in series recurring guest star Lynda Carter, who played Wonder Woman in the original TV series.

Also unexpectedly meeting up in National City’s alien bar: series regular Chyler Leigh and recurring guest star Teri Hatcher.

Here's our question, though: How did Supergirl go from day-look to night-look like that without so much as a stop in a telephone booth? Is this some new kind of power?

Wonder Womanis due in theaters on June 2.
