60s Green Flower Power Cotton Swim Top Bra Acid Vintage by Symbra Ette.

Cotton. Green background with bright pink, blue, and purple floral pattern. White cotton backing with heavier fabric in the lower half of the cup. Princess type seams through middle of cups. Fabric covered buttons can adjust straps into 3 different button holes. Because of this adjustability, the cups can be opened making it great for breast feeding. Bow at mid bust. Elastic piece at back with hooks on each side. Originally a swim top, can also be worn as a bra or outer wear! Good condition: the elastic at back is a bit stretched and the cotton is a little loose in one spot on the back of the elastic piece, small stain at inner cup, some discloration from pit to back at each side - inside only. Outside is in perfect condition.

No size tags.

Flat lay measurements
Underbust band: 16.5" (elastic band stretches about 1/2" more)
Cup: 8.5" Bottom to top, 7" across bottom of each cup
