The character Montparnasse in "Les Misérables" is depicted as a strikingly attractive figure, blending masculine and feminine traits. He has well-groomed hair and a distinctly pleasant scent, which enhances his allure. His slim waist and feminine hips contrast with his strong, military-like chest, suggesting a complex identity that draws attention from those around him.

This intriguing portrayal reflects not just physical beauty but also a magnetic personality that captivates the admiration of girls. Montparnasse embodies a certain charm and elegance that sets him apart, making him a memorable character in Hugo's exploration of society and character in the novel.
