Mercury – ☿ – Ruler of Travel (builder of trains); represents the Mad Hatter.
Saturn – ♄ – Represents matter taking precedence over mind or spirit (machines taking over); Ruler of Law (the new law of Wonderland being introduced). Saturn being the roman version of Kronos, titan of Time.
The dress is influenced by steam-punk attire, and features a neck-frill collar, a Waspie waist cincher with an attached harness, and buckled leather fingerless gloves. Her boots remain the same, as do her stockings. The bow on the back of the dress is replaced with a clock, two mechanical wings and leather straps. The apron is made of leather, and features the astronomical signs of Saturn and Mercury.
Hollow Yves takes the form of a bow again, but much more stereotypical and similar to a classic bow. The skull is replaced with a green watch, which has the appearance of glass and is surrounded by a bronze metal border. The fairly torn and worn bow is similar to steam-punk "bat" wings which stick out on either side of the clock.
Although the dress was based on Hatter's Domain, it was not based on the Hatter himself. The Hattress was the Hatter-inspired DLC dress.
