- Her most flattering haircut is often a "pixie" cut or another boyish style. Longer hair makes her look less beautiful, not more beautiful.
- The Gamine looks appealing, rather than silly, in iconic "boy" items such as a T-shirt, a hoodie, a flat cap, or high-top sneakers.
- The Gamine looks her best with very little jewelry.
Which isn't to say that Gamines need little detail. They look great with a lot of detail in the clothing -- pockets, buttons, cuffs, etc. But the jewelry is best when it's minimal. A lot of jewelry = girlish, and girlish context around a Gamine will make her look masculine.
The apparent color of your skin changes, for better or worse, depending on what color is next to it. That's because of simultaneous contrast.
And the apparent qualities of your face and figure, including the apparent masculinity or femininity, change depending on the context that surrounds it.
If almost everything in the frame reads as boyish, then the viewer mainly notices what's not boyish - and so the Gamine's feminine qualities actually stand out more.
Surround them with traditionally female decoration like long locks, ruffles, and lavish jewelry, and they become less lovely.
For one, Classics literally need every hair in place, while Gamine hair looks better with some tousle.
(Tousle suggests motion in the hair. Details that makes us think of movement -- such as zigzag lines, nautical themes, running shoes -- are generally good on Gamines. That comes from the boyish quality. When think of boys, we think of bodies in motion.)
Classic or Gamine?
And Classics are particularly lovely in their palette's neutrals and understated colors, while Gamines are particularly lovely in highly contrasting color combinations from their palette. (Again, it's about an impression of movement. Neutrals feel still; contrasting colors feel energetic.)
Gamines (and Ingenues) are tiny, right?
What I've come to believe is that the Gamine and Ingenue quality of petiteness is more about impression than reality.
Big eyes, high foreheads, round heads, slender necks, and heads that look large relative to the size of the body are characteristics of children. So these features read as youthful.
Dress a person with these features in similarly youthful clothes, and it will look right.
But don't assume Gamine (or Ingenue) based solely on small stature, and don't rule it out just because you're not petite.
