Modest Skirt → Mature Dress

Let's see... I think that, for a pair(?) of Queens, the twins seem kind of... childish? Like, they're still dressed like Princesses instead of 'Queens' so I want to try and change that. I replace 'Modest Skirt' with 'Mature Dress.'

The corridor races away behind the twins, ending with an open window as the twins' posture shifts, as does the younger(?) one's body, until they've become near perfect mirrors of each other. Then the pinks and reds of their skirts and sleeves turn to blues, and the front halves of the skirts... get smaller? They retract along the front until they're more like tiny maid aprons one stiff breeze from flashing their womanhood to the world.

I think it interpreted the phrase a little differently than I intended, but I'm not complaining.
