Good point. This also means that at some point she has to change back into her clothes. And going back to the shop to do that? Do they let you do that in the US? It's a bit bizarre to walk in a shop twice to get changed into clothes that you don't even buy there. Could it be that the clothes were waiting for Sophia in the shop or the shop owner is in cahoot with Aiden?The last render, Sophia has her purse in her hand. Chronologically where are we? I think Sophia has just arrived after she changed. I don't think she leaves her own clothes, and bra, next to Aiden's bike.
My guess is Sophia's car is nearby.
