I saw this dress in a photoshoot on pinterest, and I spent hours on the internet trying to find the dress! I finally found one in my size, unworn, and I purchased it. It turned out that this dress didn’t quite work for the look I was going for, although it’s absolutely beautiful. You can see the photoshoot at this page (and note that there are a few different dresses on this page– it’s the one with the bride on the horse): https://www.oncewed.com/real-weddings/irish-coastal-outdoor-wedding-ideas/
This dress has never been worn or cleaned. I keep it in my closet with my other formal dresses. (I've only had it for a few months, so there was no need to preserve it in any way.)
