Vintage peach Mother of Bride dress

This is a vintage Mother of Bride dress in wonderful peach! has attached lace jacket and large swing ruffles on bottom. it was worn once in 1990 for a wedding and been stored in dress bag zipped up. no size but I included measurements. my guess is a 18. This is so pretty and is fun and flowy. Excellent vintage condition! pit to pit is approximately 24 inches and top of shoulder to bottom of hem is approximately 44 inches.
