Uncle Hobart takes Beezus, Ramona, Howie, and Willa Jean shopping for their wedding outfits. Howie resents being the ring-bearer, which he feels is for little kids, and he complains about shopping. Beezus and Ramona agree to wear the pink dresses that Willa Jean likes, while Howie protests at the little suit and knee socks he must wear as ring-bearer. Once their shopping is done, Uncle Hobart buys double-scoop ice creams for all the kids, impressing the girls. Uncle Hobart orders flowers from the florist and assures the girls that the church and caterer are all set, and that wedding planning is easy. Ramona thinks that Uncle Hobart will probably forget about something, but she is excited to get her bridesmaid dress.

Aunt Bea stays with the Quimbys to prepare for her move and the wedding, making the household busier than ever. Mrs. Quimby has a baby shower, and Aunt Bea’s wedding presents begin to arrive, too. Grandpa arrives from southern California for the wedding and predicts that something will go wrong, worrying Beezus and Ramona.

The night before the wedding, the dresses are still on their way, and Uncle Hobart realizes that he didn’t order flowers for the church decor.
