Chosen by One Day Kingston dress

Wore this dress to my wedding, it’s been dry cleaned and it great condition. I added pearl buttons on the zip closure in the back. The designer labels the color of the dress as natural. I’m between a US size 4 or 6. This is an Australian designer and the brand size that I purchased is AU size 4. My measurements are: height 5’9 (with heels); bust is 36”; waist is 28”; and hips are 41”
