Formal dress for weddings or prom - Size 4-6 / S-M

I bought this beautiful dress few years ago and wore it once only at a wedding . It is in a perfect condition , suitable for weddings/engagement ceremonies or prom . - It fits well if your height is 5.4- 5.6 ( 165cm - 170 cm) and your size is small - medium . - ( My height is 5.4 and my weight was 141 lb when I wore this ) . I bought it for $650 + tax , willing to sell it for $300 *** I live in Richmond Hill , Ontario and I’m willing to meet up in person in the GTA
