Sunday Best backless tie up Dress

Sunday best dress is in excellent condition. The top and the skirt are double lined. Back ties up so you can adjust it to your size. The photos make the dress look white but it’s a light peach. The photos I’m wearing it in is the actual colour. Tied it on so you could see how it looks as it’s hard to take a phot of. Selling it as it’s too big for me. The waist has some stretch to it but there is no elastic From waist to hem is approx. 18”
