When something is exquisite, it is perfect. It is written to perfection. It is cooked to perfection. There is nothing more you can do to make it more perfect. It has met the perfection goal.
You look exquisite. You are finished and your hard work has produced a person who looks the part. Your nails are perfect. Your makeup is not too much, and you look the part, with some humility. You are not proud, but you carry your confidence well.
