Cute open back boutique style dress light turquoise and pink floral

Love love love this open back, short, lightweight floral dress. Color is a light muted turquoise with pink flowers. Slightly puffy shoulders with a flowy skirt and zipper at waist. Button class at top. So beautiful on and I wish I could still fit in it! Worn 3-4 times. Perfect summer wedding dress or cute dinner date dress. Can’t find a size but fits like a 4-6 or S.
