Ishtex Litte Ann and‎ Dan Dress

This dress was new with tags, but one sleeve looked discolored. I took the tags off and washed it in All Free and Clear. The one arm still looks slightly different to me. I don't know if it's the lighting or its slightly different. I do not think it would be noticeable at all, but I don't want to sell "new with tags" if it's not perfect. Little girls size 8.
