Hi Rita, I designed this same style in 2000 for a bridal party (The Maid of Honor), and the difference is that it was a gown made of Lavender Silk Charmeuse with an over-lay of Plum "Twinkle" Chiffon. The one cross strap was made of Beaded Lavender and Plum on organza flower trimming about 3/4" wide. Made on the bias with a split in the back hem.
It was beautiful...all I can say is good minds think alike ; )
I like the fabric you chose. Beautiful contrast of colores.
I've been designing for 30 year's working bride's, prom's, private cliental, along with your average alteration's...I love it, its my passion!
