This costume first appeared in the Roll-Call shot for L* #46, seen above, and she didn't appear for the rest of the issue.  In fact, previous images from the issue had been in her last costume.  When the next issue came out, Zoe was back, and in this costume.  It just kinda appeared.  Safe to assume, of course, that Zoe just up and changed her look on a whim (Gee, she'd never do that), but most of her other changes that I can think of, have been on panel.
