Virgo doesn't like revealing her true identity to the people of Altale due to how the Pannanians react when they see her. Said Pannanians would praise her to the point of giving her less freedom. Thus, to avoid getting a lot of praise, she disguises herself as Miranda when she visits the cities.

Here's the reference.

• The flowers on the heels can be simplified.
• Exclude the wings for this outfit.
• Exclude the Virgo sign on her left cheek. This is important because she doesn't want to get found out by her people.
