Right now with no skis on, stand up. Decide which shoulder you're most comfortable looking over while skiing switch (you're gonna wanna use both but for learning do what's easy. Stagger the foot on the same shoulder you want to look over about half a step. Turn your hips, shoulders and head towards that staggered back foot. Bend your knees slightly and weight your toes and balls of your feet. That's the stance.
to get really good you'll have to do it both sides but you can get a lot done with just one. It's not that hard, just pick a green and start practicing finding your edges and linking turns. With just one shoulder peek, you'll notice that when you turn one way it'll be easy and natural as you can really lay into the staggered foot and track, the other way your stagger will lessen and it'll feel a lil weird at first. You can always turn your head to look the other way and change the stagger of your feet to match but I find most beginners struggle with that
