But why the ___ for Gemma? S2E7

Here’s what I don’t get about Gemma and her testing: why dress her up, complete with wigs?

It really hit me when she was dressed so 1980s for the “plane ride”. What is the point of that? There aren’t mirrors for her to see herself in the costumes, so it’s not for her. (And even if it were, all her innies would remember is that they were wearing a wig. Wigs are itchy.)

So who are the costumes for? After the Xmas “marriage fantasy”, I kinda thought it was for the doctor (so he could see her as he wanted). But it doesn’t really track for the rest of the rooms. The only one that really made sense to me was the workout wear for what presumably was a workout test. But why make her carry a (presumably empty) purse into the dentist’s? Why not let her have her own hair showing?

The only thing I could think of was that they are filming this for someone else. Maybe higher-ups, maybe promotional materials? But if the theories about selling the chip to people who want to avoid tasks are true, would they be implying you’d need to dress up your innies for those tasks? I just can’t wrap my head around the point of the costumes. (Apologies if this has been discussed, I did search but didn’t find anything.)
