Ingenue beauty is often what you're seeing if someone is clearly "pretty," but you'd feel uncomfortable styling her in overtly sexy clothes because she just looks too darn sweet.
The curving line is the defining line of all the feminine types, but Ingenue's circles are small and restrained, rather than large and lush.
Ingenues look appropriate, not ridiculous, in girlish details such as small bows, tiny flowers, headbands, simple lockets, and puffed sleeves.
The Ingenue face is quite round, with a tiny, tapered chin, a small, pert nose, round, wide-set eyes, a large forehead, round cheeks, and plump lips. Ingenues often have naturally curly hair; if they don't they are still flattered by curls. Overall, an Ingenue reads as girlish.
By contrast, they look silly -- like a kid playing dress-up -- in anything "sexy" or womanly, such as elaborate jewelry or a plunging neckline..
And of course, Ingenues are no less sexual than any other people. It's just that visually, they read as girlish rather than womanly.
Eyes that appear very light relative to the overall coloring read as youthful, and therefore Ingenue (or Gamine).
Note that this signifier should be interpreted relative to the overall coloring. On a pink-skinned, yellow-haired person, deep blue eyes probably won't read as Ingenue. On a brown-skinned person with black hair, caramel or light brown eyes will read as youthful.
Ingenues appear authentic and relaxed with sincere, joyful smiles.
Ingenues often hear "pretty," "cute," "sweet," and "adorable." They're not perceived by strangers as intimidating, mysterious, tough, or intense.
This can be frustrating to an Ingenue with a more assertive, competitive, or no-nonsense personality.
If that's you, my advice is to take advantage of the element of surprise that your innocent appearance grants you. They won't see you coming. :-)
