vintage oops california denim dress size Large blue jean purple acid wash 90s

This dress has half sleeves, a purple acid wash look , collared neck and half snap button front with two side snap pockets. Possibly 90s or 80s. Approximate measurements: 21” across chest 45” long (fits like a midi for most) Please note this does not have a size tag so I am estimating this to be a modern size large based on my measurements. Please compare my measurements to you so you can confirm a correct fit. I think this could also fit a size Xl but just with a more fitted look.
