This is an issue for me too, I have full sleeves on 1 arm and both legs - it’s very tricky but I use long, thick stockings or crotchless tights (great for hiding everything on your legs except for your lady parts, obvs!), curtains with voiles come in handy for photos, and for videos I blur whatever I can using an app called MovStash.
I don’t have many videos though because it’s so hard to cover or blur everything
