"Maybe it'll help if you take your shirt off first," you say, wondering how she wil react.
Amanda looks over at you in confusion, "What? How will taking off my shirt help any? I'll be even less dressed than before!" You briefly consider just taking it off for her, but you want to see if you can convince her to do it herself first.
"Well, when you're naked, what do you put on first?"
Amanda furrows her brow in thought, then frowns, "I... I don't remember. Oh God, why can't I remember that?" She starts hyperventilating. Uh oh, this could be bad.
"Calm down, and think about it," you say, before adding the command, ~You won't panic or break down over forgetting something, because you know I will help you if you need it~. You figure that should be enough to prevent any unexpected panic attacks in the future, and indeed it does calm her down a little. You make a mental note to remember to place a similar command on future targets earlier on.
"I... I still don't know," Amanda repeats, still looking worried but at least no longer on the verge of a breakdown.
"Your underwear," you finally tell her, as if you're explaining it to a child, "You put on your underwear first, which includes your panties. You might just not remember because you're doing things out of order, and it's confusing you. Try taking it one step at a time. Take off your shirt, and then you can just think about putting your underwear on."
Amanda fidgets nervously, "I'm not sure..."
"Look, I'm trying to help. If you have any better ideas, feel free, but if you're just embarrassed to take off your shirt in front of me, I should remind you you're currently bottomless in front of me and asking me to help you put on your pants. We're kind of past the point where being shirtless is an issue, don't you think?"
Amanda's face goes red with embarrassment, then lifts her shirt up over her head. You end up having to help her get her arms untangled, but before you know it Amanda is standing in front of you in only a bra, her shirt lying discarded on the floor alongside her slacks.
"Sorry," she says, "I just... I didn't realize I had to take my arms out too."
"It's fine," you say, grinning at the realization that Amanda might now need help getting undressed as well, "Now, try the panties again."
She nods and picks them up off the floor, then frowns, turning them around in her hands once. Then twice.
"I still can't figure it out," she admits in frustration.
