'Dress down' wedding outfit

[PolaDeVeboise]

Hi ladies, looking for some advice. I am due to attend a relatively informal wedding in May - it's in a hotel, but the bride and groom are bikers. I have bought a (maxi dress, 18, made of chiffon (pic attached shows purple but it's a 'midnight' blue and was looking of ways to rock it in a 'cool' way, rather than 'glamorous', if that makes any sense. Looking for jewellery/headwear/footwear suggestions. Don't want much, do I?

Leather jacket. Ankle boots/Doc Martins. Statement necklaces that aren't pretty - surprisingly John Lewis do some good ones here. Primark too.

Thanks Uppity, but that's a bit TOO 'down' for me, besides, I own neither!

I'm not great at accessorising but love that dress. Could I ask where it's from please?
I'd go for a bracelet and statement earrings.

I wouldn't veer too far from your usual style.

Not knowing what that is I'd suggest flat beaded sandals of some sort and a flower in your hair in a contrasting colour. Or do that hair where its sleeked back at the sides and volume on top.

Bag wise i wouldn't go with a clutch anyway. Too chic. Something with a strap.

Not too matchy matchy but eclectic a bit. A jacket could help but it would probably be very hard to find the right one.

Second Honeymoon, its from Scarlett & Jo. Never bought anything from them, but I'm well impressed, it's gorgeous in the flesh.

I thought that too Never re jacket - a difficult one - may have to do the pashmina thing, but then that's really weddingy!

This necklace would give the dress a completely different, cool vibe:

A friend has suggested black suede ankle boots and black jewellery. Think I'm going to go with that, but thanks for all the suggestions.
