Yup, a very good hint is the one about the elbows...
Men walk with elbows out, kinda like a gorilla or chimp. The palms of their hands often pointing towards the back with all the fingers curled slightly.
Walk with your elbows in, so you can even feel them slightly graze your hip bones now and again. This forces the palms of your hands to face more towards the front, the index and middle finger a little more pointed than the rest.
It's a subtle difference but look for it in walking girls...
