Gap denim dress - high button-down collar, 3/4 sleeves size XL

I *love* this dress but it does not fit anymore. It's a faded black denim dress with a high button collar and three-quarter sleeves in size XL. It has a matching denim tie belt and string loops to hold it up. Hits around the knee on a 5'7" person. It's a soft denim, no stretch. Very comfortable, yet still looks fashionable and professional. In good used condition. From smoke-free, cat-friendly home.
