It honestly depends on what he finds sexy or attractive. Some guys prefer girls more covered and only hinting at skin and some prefer way less. Also the style and color changes the effect. Your body should also be taken into consideration. Does this outfit show off good parts of you or does it look odd in certain places? Because oddly fitting clothes aren't attractive. There's a lot of factors to consider. So maybe ask him what he likes without giving away what you're thinking about wearing and take it from there?
