"I feel, he love me. He still love me...
I never thought, that love can hurt so much..."
An outfit for Chrysa in my imagination.
The queen made a pact with Princess Celestia, and in exchange, she save Princess Cadance from the Crystal Empire, when King Sombra returns and defeat Shining Armor.
Chrysalis sacrifice herself as a fake Cadance, and become the captive of King Sombra. When Sombra see her real form, he fell in love with her and want to make her to his queen.
This dress and jewels are his gift.
As the events unfold, Chrysalis face a hard choice: the colt, who love her for herself, and with him an evil path again... or she do, what is right and help Princess Cadance.
