I now choose to believe that every one of Tracer’s skins has been something she has worn for an event with her girlfriend.
The punk costume? They’re going clubbing, Emily has worn a black tank top and can’t stop laughing because pink hair Lena, really?
The Olympics skin? Gotta get hyped for the season. She wears it for a watching party at a mates house. Emily is dressed up in a simple jersey.
The Christmas costume? Emily’s office party. Emily laughs because she always knows where Lena is. She has worn an ugly sweater.
On the flip side, for Halloween? Lena didn’t put on a costume because she didn’t have time while Emily has dressed up as her favorite superhero.
Let’s say when Lena gets home, her jaw drops at Emily dressed up as her.
