This is a Peruvian Connection Brown Long Tank Top that is a size Medium. It is 93% Pima Cotton and 7% Spandex. Laying flat, it measures: Armpit to armpit-18" and the length is 30". It is in great condition. Very soft. Please measure something that fits you laying flat. The length is measured from the shoulder to the bottom hem. I measure pit to pit laying flat for the Armpit to armpit measurement. This is for both our benefits so there will be no hassle of returns for not fitting. Thank you in advance. If there is a return, I will not refund the shipping cost, so please check the measurements before ordering.
