Lizzie y Miranda salen a comprarse su primer sostén.

Lizzie and Miranda note that when a girl gets her first bra, her personality somehow seems to change. They decide they are ready for their first, and hatch a plan to get Lizzie's mom to take them to the mall where they will shop for ""school supplies."" Lizzie is a terrible liar, though, and blurts out the real reason for the trip. Mom is overjoyed to help the girls out, but she embarrasses them as they are shopping. Lizzie is very harsh with her mother, telling her that she and Miranda are old enough to do their own shopping and to leave them alone. The girls face further embarrassment when they run into Kate, Claire, and their English teacher Mr. Coppersmith. They also find that they don't know what to look for.
