Hey there! I'm Shay, the brains behind Alice Liddell. There's this scene in the Disney films (I'm sure you'll remember if you've ever seen it) where Alice falls into a rabbit hole, and her dress opens up like a parachute to land her to safety. Maybe Arachne made/makes a replica of that dress for Alice? She's pretty reckless, so I'm sure a lifesaving dress would benefit her!
