Shopaholic and Sister (2004)

In Shopaholic and Sister, endearingly upbeat (and always chic) Becky Bloomwood returns from her around-the-world honeymoon to find a long-lost sister, Jessica. But hopes of bonding are dashed when Becky learns that Jessica — gasp! — is a social activist who abhors shopping. As Becky surprises Sis by infiltrating her (formerly) simple life in boutiqueless Cumbria, Kinsella unfurls more of the same fun, label-obsessed high jinks for Shopaholic fans.
