Tags on. Neve worn. This is XS but it is adjustable to likely a S or and M if necessary as needed because the string can be tightened or loosened depending on the chest circumference or look you are going for. Ie can be very low in the back for a more backless look or higher up if looking for a more subdued dinner look. Super comfortable and very beautiful just have nowhere to wear this. Hope someone can use it well:)
