Free People Peasant Button Down Top w/ Lace Detail

This top is beautiful with really cool dolman like sleeves. It is labeled as an XS but in typical Free People fashion, this is quite oversized. I am a M/L and this fits me comfortably. Anyone XS-M/L could go for this! I purchased this from a high end consignment shop and found a stain after getting home. I have washed and treated this, hanging to dry. I have not tried a bleach treatment.
