Beautiful Windsor long dress

I've literally never worn this dress. I put it on a few times I prance around the house in it a little bit and then I take it back off and I hang it up. It should get some use; maybe for Christmas or New Years. :) I am 5'10, 160 lbs for fit reference. I found a few loose threads around the hemline and perhaps a few spots of discoloration that I tried to document. One is on the inside underneath the tag so not visible.
