Please help accessorise me for a posh event

[LifeBeginsAt46]

I am incredibly clueless about fashion and would appreciate help to style this dress. I'm going to a fancy outdoor event and need a jacket, fascinator or hat, shoes and jewellery to match. I'll be standing up for several hours, on grass! TIA.

I’d definitely go for gold sandals, gold earrings and bracelet and a green hat or fascinator to match the shade found on the dress. You could of course match the hat to the bag and have them in matching colours.

Also, a raffia style bag and espadrilles would look lovely.

These are lovely, and should be a good option for standing on the grass!

Definitely wedges or espadrilles to avoid the stuck in grass!

Ooh thank you, the shoes are perfect!
What colour jacket would you go for?
