Two things

1 - "It's Morphing Time"
2 - Her panties are on the outside.

Yes I did that to see if the suit would look more like a "superhero" costume. You know how Super Heros always wear the underwear on the outside.

who was the one that made underwear an outer garment for superheros and WHY?

it goes back to the early 20th century. Back at the end of the 19th and the start of the 20th century "Strong men" at shows and FAIRs would wear nothing but body suits and Underwear on the outside of the body suits.
To show a Comic character was "strong" like a strongman they'd dress like one (most famus, Superman). Like how WWF/WWE Wrestlers most of the time just wear boots and underwear.

Did you make that suit or is there one for it out there?

I mean her Assault uniform.
