This is an unusual dress from "Matilda Jane" that is very long. The sleeves may best be called "diagonal," which is combination of cap and short. The cloth tags are present EXCEPT the one for size, so I'll provide some measurements: - Pit to pit = 20 inches - Tip of one shoulder to center of waist = 24 inches - Bottom point of V-neck to center of waist = 17 inches - Center of waist to hem = 43 inches I think the overall size is medium or large. It's not small. Lengthwise, it's definitely for a tall person or would need to be hemmed. The fabric is 95% modal; 5% spandex. The dress does have a lot of stretch--especially with the three bands of elastic--two for the arm openings that run down the sides to the waist; one for the neckline V (that runs down to the waist on each side); and the waistband itself. The fabric is not lightweight, but more the weight of a men's T-shirt. Thanks for looking!
