Summer evening soirée accessories help please

[goingdownfighting]

So, I've been invited to a family wedding summer soirée in Greece this summer. The dress code is smart casual summer wear.
I'm 5ft 2 curvy size 10-12.

I've fallen in love with this dress.
I have a lovely seamstress who can fit it to me better if needs be.

So I need your esteemed opinions as to whether it's suitable and how to accessorise. I was thinking of gold layered accessories.

Please bear in mind that most of my family look like supermodels (no really it's shit, plus they're all lovely and kind), I'm the oldest, only one with a mum bod (diet has started).
I can't compete but want to feel comfortable and fabulous. And expensive. And understated. That's it.

Help!

I think it's a gorgeous dress! Really stylish and perfectly on brief.

I think gold is a good shout. If it was me, I'd be inclined to keep the photo styling and go without a necklace to keep the neckline clear, then perhaps add a fabulous pair of gold hoops or gold earrings with a stone that pulls out the dress colours (green, pink etc).

I'd also go with a gold clutch to avoid ruining the floaty lines of the outfit with a long strap/across body strap. Maybe a gold leather slouchy clutch number? Or how about a hand held beaded number?

Then gold or dark green velvet platforms - or alternatively an embellished flat if you'd rather?

Ah thank you. Great call re: no necklace and clutch bag. Would gold earrings and a cuff be too much?

I think it will need to be heels as the dress is for 5'3 and over. I have some metallic wedges that will be perfect.
