Mirabelle is the "shopgirl" of the title, a young woman, beautiful in a wallflowerish kind of way, who works behind the glove counter at Neiman Marcus "selling things that nobody buys anymore..."

Mirabelle captures the attention of Ray Porter, a wealthy businessman almost twice her age. As they tentatively embark on a relationship, they struggle to decipher the language of love--with consequences that are both comic and heartbreaking. Filled with the kind of witty, discerning observations that have brought Steve Martin critical success, Shopgirl is a work of disarming tenderness.
