Had a long Thai Silk, off white, with Military style collar, so I could attach my Mother's beautiful brooch as my 'something old'. It was just 'normal' down to waist & then flared-out at one side with inverted pleat.
My 'going away' outfit was a full length Watermelon' coloured coat over the top. Both gowns were worn as Ball Gowns for a few years, as this is what I wanted, so could get use out of them.
My shoes & clutch bag were made in Hong Kong, with same material covering as dress.
Eventually gave them away to charity.
