Some great advice already, and remember that most people are too wrapped up in themselves or their smartphone to notice you, except for adolescent boys showing off and hassling you and little kids (best avoided).
On the walk, a detective I know said he always knows if he is following a man or a woman by their footprints, and no not because of the stiletto heels! Men leave footprints in two rows, like a railway line. Women leave a single line or close to it, they walk heel to toe. They also tend to plant their toes or a flat foot whereas men tend to put the heel down first. Doing heel to toe naturally gives your hips a slight swing as you walk, and remember chin up, shoulders back and chest out as they used to say.
On hands, if you look women usually bunch their fingers slightly to form a smaller hand. Men don’t, their hands are big, meaty things. Women often walk with one arm slightly lifted at their side (holding their handbag for instance) and what arm swing there is diagonal. Men swing arms like gorillas back and forth.
And the biggest thing is women SMILE when they walk, men don’t!
Go and enjoy it!
Hope that helps!
