Speed dating gives the styling a real constraint: a few minutes per person, so whatever the outfit says has to arrive immediately.
That rules out the subtle end of the wardrobe. What works is one clear signal, and the two sisters should not send the same one, because the whole point of them is that they are opposites. Elsa's version of an entrance is restraint carried perfectly; Anna's is warmth and a bit of mess. Give them the same dress and the game stops making sense.
Longer than the average Frozen scenario here, which suggests people do stop to think about the pairing.
