I'm currently playing the original game, and I notice some of the rival competitors in the international fashion contest come into my boutique just to congratulate me in a very backhanded way and tell me that they'll beat me somehow.
Ignoring that, I'm debating adding them to the Customers page since, A. I don't actually know if they actually are, and B. they all seem to have the same budget and similar bios. Regardless, they all have stamp cards.
For any experienced players, what's the deal? Are they just rivals, or are they actual customers?
I only have LQ pics of Lilija and Naledi:
