Deep V backless maxi dress

The top of the dress is crocheted/cream with no stretch and has a tie halter strap and a low back. The rest of the dress is a very loose stretches flowy material. I wore this with platforms sometimes or as a swim cover-up others. It’s perfect for a beach vacation! Please note the gray discoloration on one of the straps. I haven’t tried to wash it out so I’m not sure if it will come out.
