Ugly Me (2006) on Netflix

Plot summary

Amanda is an architect in Santiago who finds her boyfriend Pepe with her friend Fernanda, threatens them with a shotgun and loses her job. She moves to Valparaíso, rents an apartment for six months and befriends brother Juan at a church there. To keep men at a distance she builds a disguise of a fat suit, dentures, a wig and unflattering clothes, then takes a lower-paying job at an office run by Max. Her new colleagues include Guillermo, a married family man, Karen, a recent graduate, and Marcelo, a womanizer who is repelled by her appearance and whom she finds repellent in turn. Max sends Amanda, Marcelo and Guillermo to investigate a maintenance problem at one of the firm's projects.
