This is a light blue, short-sleeved top featuring a square neckline and a button-down front. The defining characteristic is the smocking around the waistline (and sometimes the cuffs or bodice, as seen here on the cuffs), which creates a gathered, elasticized, and fitted effect before flaring slightly at the hem. Its overall silhouette, often with a gathered or puffed sleeve, is typical of the peasant style.
