The Summer All The Time Collection was produced by amateur fashion designers Phineas and Ferb, with help from Isabella and the Fireside Girls. Gaston Le Mode appropriated the designs to use in his fashion show. The clothes were modeled after Phineas's and Ferb's signature look. Candace was asked by Gaston to wear it, but she refused due to Phineas and Ferb's influence in making it. Gaston's models wore it down the runway, which set off a craze throughout the Googolplex Mall, with everyone wanting to wear it. Stacy wore one that was modeled after Ferb's usual outfit, except for the shoes ("Run Away Runway").
