Beach cover-up, sun dress

Navy and white tie dyed patterned sun dress/swim suit cover up. No inside tags and I believe this was purchased at a craft show. Material is probably rayon and can be washed in a gentle cycle. No tags, but I wore this when I was a size 6. Gently warn in good condition. Cute pattern. Measurements: Arm pit-6” Straps-4” Length from arm pit-23” Waist-15” across
