DATE OUTFIT URGENT

Ok so I need advice for a date, we're going to a movie and then for a meal at a casual restaurat. We are close in terms of us having 'got together' but it's our first time on a proper date in a public place. I don't know if I should wear skinny jeans? Black or stone coloured? Can I wear a turtle neck top? Everything I wear seems too much or too little? Shall I insert photos? I DONT KNOW WHAT TO DO. also I want to be WIFE not girlfriend material so up don't want too show too much skin!!
