My gown is in pristine condition and has been freshly dry cleaned. It is a beautiful classic style and falls beautifully so easy to wear and comfortable but still wow factor. The top is sheer giving the appearance of strapless without the risk of falling down/ moving around it is made from silk and is hand pleated so the detail in it is exquisite while still
Being simple and understated. It is from the USA from a designer called J.Mendel and cost me AU$7k from Anna Dafonte in Paddington which has now closed down. It is currently on sale on Shopbop for US$2880. I would be happy if I got $2000 for it but negotiable. If Sydney based happy to arrange a time to try on. It was made to fit me I am tall 5ft 10 and a size 8/10 so could do some small alterations to fit you.

Description by designer as follows:
Graceful pleated silk cascades through this floor-length J. Mendel gown, lending ethereal volume to the romantic silhouette. Crossover detailing contours the fitted, boned bodice, and the nude mesh yoke offers invisible support. Pearlized beads shimmer along the optional sash, which ties at the ruffle-trimmed waist. Sleeveless. Padded cups. Fully lined.

Can send pics of bridesmaid dresses too if you want tips on styling the whole look. Also I wore stick on strapless chicken fillets as bra solution and worked beautifully.
