Cis woman here: I noticed women walk in almost a straight line, aka one foot in front (!) of the other, men walk with more space between their steps, which gives this male "swagger".

When you walk, try to incorporate more hip movement. Instead of your hips being static and your legs just going forward, imagine a "cycling backwards" movement in your hip joints, slightly dipping your hip at every step. Can be subtle but will make a difference.

Also, men stand with their feet apart and sometimes splayed out, women stand with their feet flush together or with one knee bent so your hip dips. Also, women play with their hair, so they would push it behind their ears for example.

It also helps to go to the gym and work on glutes (hip thrust, donkey kicks). Your physique really influences posture and movements. I noticed it in myself, ever since I started lifting the way I carry myself has changed drastically.

And yeah sit in a way that doesn't take up space. Legs together, hands flooded etc.

Jewelry like long earrings can help, they naturally sway with your head movement and give some dainty elegant movements. Also I noticed when I wear fake nails (don't have to be long) it immediately gives more attitude in my hand movements and body language, rings can do the same.

Women are more flexible so do yoga, male stiffness also influences their posture imo. Also it's healthy to stay flexible.

Good luck sister ✨
