I ended up wearing a different gown for my wedding day. Please message me and make an offer! Happy to send more photos. This is in its original packaging sent by the designer and all of extras (cups, white gloves) available.

Description from the designer:
This gown is in their exclusive 'Ivory' heavy 100% silk satin. The Crest features a perfected, streamlined 1920's 'seamless' molded body, a deep 'V' neck and backlines, fine silk satin shoe string looped straps fixed under the back arm, finished by a flowing, circular 'half moon' train.
Mixing feminine flair with refined old world elegance, this timeless gown boasts delicate shoulder straps, a deep open back and a sculptured train.
The Crest is a perfect 'less-is-more' silhouette which can be worn again for any high end event, or as a base to any of our French lace and silk tulle overlay gowns.

T-shirt/modesty bra cups are included with order to ensure a smooth and modest finish across the bust.
Hem is finished to a 47" length from waist to floor at centre front of skirt. All Gowns come with finger loops, hook & bustle options, bust cups for modesty, and cotton gloves for dressing.
