Size 6, fabric is luon. Pit-pit: 16.5”. No size dot because this style doesn’t have one, and I ripped the tag, so measurement is provided. Small tiny snag on the thread that can be snipped off. Love this style so much and I have the matching pants. Unfortunately its way too big on me now. Can even fit an 8 or 10 because of its stretch Don’t hesitate to bundle or offer! Cross listed
