46% Modal, 46% Cotton, 8% Spandex. Machine Wash Gentle in Cold Water. Hang or Lay Flay to Dry. Do Not Bleach. Do Not Iron. Double layered front 3/4 length sleeves Ultra soft Modal/Cotton fabric holds shape and is meant to hug your natural body without being restrictive like shape wear. I loved this but I needed a medium for size. Only worn once. Willing to negotiate on price since I’m moving and need to get rid of clothes.
