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