Shoulders back, chin out, neck long.
Breasts out shouting to the world,
“I am here. Look at me!”
Long neck highlighting a feminine jaw and cheekbones

So instead,

Shoulders hunched and chin down.
Breasts hidden among the folds of fabric,
“I’m hiding. Shhh.”
Neck hunched over. Eyes looking at the ground.

But men do not walk like that,

So instead,

Shoulders back, chin out, neck long.
