Dessy Group is a global leader in social occasion dresses and wedding apparel distributed through speciality shops and department stores in the United States, Canada, UK, Ireland and Australia.

Dessy Group got its start in 1939. Originally known as A & M Rosenthal, the company produced bridal veils and headpieces designed by Margot Rosenthal. In the 1950s, Margot's daughter Ronnie and her husband Andrew Dessy assumed leadership and added bridal and bridesmaid dresses to the company's lines.

With the third generation, the business became known as The Dessy Group. Alan Dessy and Vivian Dessy Diamond strengthened the focus on bridesmaid dresses and added social occasion dresses and menswear to the lines.

Today Dessy Group is the go-to company for several top brands in wedding and special occasion fashions including Dessy, After Six, Alfred Sung and Jenny Packham.
