Generally, if you want your walk to be/feel more feminine, you'll want to essentially mimic walking in heels. If you don't know how to walk in heels, it's all about planting your feet in one straight line and walking along it. Go slow at first. Literally take one foot and place it directly in front of the other one while being a normal walking distance. Get used to that feeling. Then take the heels off and mimic it. Do it whenever you can think about it. Try and walk slowly. One foot in front of the other just like in heels, think of it almost as if you're crossing them, just to make sure you're doing it right. Walk with your back straight, and keep your shoulders still and back. Movement should come from the arms and be minimal. If you carry something, make sure you hold it against your chest/torso instead of under your arm. You can try and rock/sway your hips, which essentially just means turning them as you walk. Lastly, try not to walk too fast. Women do walk fast, but at the start you can forget allot of the things we just talked about. So walk and move slowly and deliberately. Make sure that when you do walk you aren't bobbing up and down. If you can see yourself on camera/record yourself then great. You can see what you might be doing wrong. Good luck!
