Sleeveless linen Wrap Dress

The tag says 12petite but I felt it was oversized for me (a Size 8/Medium) Loose fit 55% Linen, 45% cotton Shin length (I am 5'6") Smock-like/canvas-like style This is in good condition. One of the buttons feels a little loose. Other than that, there are no stains and no apparent snags in the fabric. I wish this worked out better for me or that I knew how to sew to take it in a little!!
