NWT madewell white v-neck sweater tank. Very comfy and versatile top (I own it in multiple colors lol). Personally i think this also fits a size small well.

Crop length: designed to hit between the waist and high hip. Body length from high point of shoulder: 16 3/4" (based on size M). Viscose/polyester. Machine wash.
