yes, this is a pajama top but why limit yourself! look at that peter pan collar! the daisy buttons! whimsy! piping along collar, sleeve cuffs, and button placket. looks great under overalls or vests, or worn over a tank top. perfect for summer with how flowy and lightweight it is! measurements: 23.75" pit to pit while buttoned 23.5" shoulder to hem Btw the true color of this top is in the closeup photos! Definitely periwinkle as opposed to the darker blue shown in other photos.
