Super cute pink dinosaur costume in size xs for toddler. Bought this for my 2 1/2 years old daughter but it’s a bit too big for her. The next size down from this is 18-24 months so I would say this runs large as she probably would fit that one. Super cute and great quality, just didn’t fit. Brand new never worn. Please see screen shot of measurements per the Halloweencostumes.com website. Sold out on the website in this size. No returns.
