Vintage Contempo Casuals denim dress

Vintage zip up denim shirt dress from the 90’s. Marked size 5, fits more like a modern 2. Feels like 100% cotton, fabric tag is too faded to read. Very little stretch. So cute but too tight in the bust for me. Very good vintage condition, some wear/fading but no flaws to note. Bust: 16” Waist: 14” Length: 31”
