Womens Short-sleeve, button up, v-neck sweater top

This cute striped & color blocked sweater top is medium weight. It has 2 functional pockets on each side that practically “hide” in the color blocked area. There are some signs of pilling, normal wear. Very hard to photograph the pilling & not really noticeable unless photographing. There are no care, material or size tags. Based on measurements (see photos) I would guess it’s a extra large. It’s from my friends closet & she said she machine washed & dried the top. She hates to give it up but she lost weight (yay👏🎉) & it doesn’t fit (😢).
