Mauve/pinkish colored long sleeve flowy dress

I'm not quite sure where I bought this from. It's a long sleeve, loose fitting tshirt dress. I'm 5'6" and it hits a few inches above my knees! The only flaw is in the second picture right by the size tag where it has the small "hole". It's more of a snag and doesn't show through the other end of the fabric! It says size medium but it could fit anywhere from a medium to XL, depending on how you want it to fit!
