Runway time! The guest judge is Monique Lhuillier (can you say Lindsay Lohan upgrade?). Louise, Mitchell, Althea, Malvin, Shirin, Ra'mon are among the best and the worst. Ra'mon says he created a cocktail dress. Monique says the construction is sloppy, and Heidi says the dress' patterns point to the baby. Which they totally do. Louise's red lingerie dress is a hit. Rebecca says she'd wear a dress like it on a date with her husband. The judges like its details and its tiers.
