Summer dress, one pink and one green

Light summer dress, one in pink and one in green. Bought in the Caribbean. Plain in the back, with some appliqué design in front. One size it should fit S/M/L armpit to armpit 14" to 20" stretched. Length from armpit to bottom 24" dipping another 15" gradually towards the center. Never worn. The green one is cheaper due to a tiny interruption in the green overlay motif.
