Polo v-neck ribbed long-sleeve sweater from Aritzia/Babaton. Black, size XS. NWOT/never worn. Full description of fit, sizing, etc. is here: https://www.aritzia.com/us/en/product/leyster-sweater/101505.html. Couldn't find any model photos of the black color so included one in the red/orange color so you can see detail better--but this item for sale is BLACK.
