In my Chicago based game (loosely based on the SR5 missions and running on beyond that story arc), I always played on fixer (Silverleaf) as kind of looking down at the scruffy runner team -- and there had been an escalating rivalry situation with her. The campaign eventually went to France for a while for reasons, and before heading back to Chicago the decker/mage (a scrawny young woman who'd always dressed in oversized practical clothing) decided to spend some time and karma to pick up knowledge skill high fasion and the Fashion spell.
Upon returning to Chicago the character went out of their way to get a meet with Silverleaf and showed up much more fashionably dressed. And that was when they hashed out their differences and built a bit of an alliance of equals.
