Amber Blue sleeveless dress

Brand is Amber Blue. Color is a teal green. Sleeveless dress with lightly padded shoulders. Unfortunately I am unsure of size, as size tag is missing. The dress fits my dress form which is a women's size 6-8. Flat lay measurements include: armpit to armpit 15.5", shoulder to shoulder 16", top of shoulder to bottom of hem 34", approximate waist 13.5"
