Jean denim dress abt a sz 4

French designer Regina Reubens all Denim Jean dress. Side slits abt 6”. No stretch. I LOVE this dress it’s so cute for summer but is doesn’t fit my bust any more (hence modeled with top open) Dress is darted to make it ultra fitted. European made Dress without listed size. I’d say it would fit a sz 4 maybe a 2 best but see pics. Flat measurements: Waist abt 14”. Bust about 16.5” (I was a 32 C when I wore this and would wear without a bra). Top hem to bottom abt 27.5”. Perfect condition.
