Aha! @lordcobol this episode actually hilariously has lots of actual onscreen moments of the sangtu, the manggeon, and how the sangtu is put up properly with long hair. See, told you there are benefits from having Eunuchs in Drag! hehe
Part One: The King’s Affection #2 and Joseon Hairstyles
Here you can see that actually the prince and Dami would’ve worn the manggeon (headband) and therefore the full sangtu, underneath the formal prince’s headwear, but this young actress wears the manggeon quite high on the back of her head, so it wasn’t noticeable in the last episode.
In the 4th picture we can also see the strings that tie the top knot in place also.
(also bonus, the Princess’ Rooster Hair Pin)
