This is a chic long sleeve top that you could wear more as a dress paired with leggings and either just a bralette or a cami.  It could also be layered under a sleeveless sweater or under a sleeveless dress.  It is in excellent condition and this type of material is very easy to take care of and doesn't require much maintenance.  The tags have been removed, but it's likely from H&M or Zara.  I am pretty sure it's fully polyester and it likely is machine washable or at least able to be washed by hand.
