Question: why long pants for the women in the last four, but panties in the first?
Yes, and they are all the same outfit. The bathing suit is the same outfit as the pants and top. There are numerous combinations for each.That first one isn't "panties". It's a one piece set . . . something like a bathing suit.
Wonder Woman and Supergirl in that order. I like Black Canary more than Zatanna, but both wear those fishnets.So then, who is 1st & 2nd
