I imagine the lair to be very girly and frilly, candy machines from wall to wall, with one large circular dome in the middle to show mission progress and information. All the chairs are a either a blinding white or blush pink, and would also be small enough to accommodate teenage girls. There would be a magical wardrobe to dress up in the latest cute teen trends, a hot chocolate machine, and a karaoke machine. Plushies and adorable cushions are everywhere, the walls painted white with multicolored polka dots to show the team's unity. There is also a pinboard with old pictures of the girls with the word "Friends!" in super shiny glitter letters.

Y'know, all cutesy, girly, teen girl stuff. Adorable yet out of place for women in their thirties.
