Lilly Pulitzer Sizd 4 Dress

I purchased this dress about two years ago. I took the tags off and don't think I ever wore it. It has been sitting in my closet. I was able to find one very small spot of discoloration on it (pictured). I did not try to wash it out. It is difficult to see when looking at the dress. And the best part- it has pockets! I do have a dog and a cat, however they are not allowed in the closet where the dress is kept.
