Ideas for a flattering winter wedding outfit I could wear again

[HappyNewt]

Looking for some ideas please for a Wedding dress....
Winter wedding, small hotel with 20 guests staying over...timber...fireplaces...candles.
I'm 54, 164cm size 10/12
I dont wear dresses often, I tend to prefer shirt dresses/wrap with collar..I dont mind skirt with a good shirt.
I'm just not used to searching for smarter dresses...and as the bride I want to look great.
Not looking for white unless its just thd top part.
I often wear black or indigo, and whilst I dont mind either for this I wonder if a dark green/plum might work...so looking for ideas that challenge my blue black tendancies!
It would also be great if it is a dress that I could wear again
Many thanks

Congratulations!
Perhaps evening dresses in jewel colours might be worth a look (eg Phase eight Grace). Could also consider a taffeta/shot silk maxi skirt (per Karen Millen) for a lovely silhouette along with a champagne silk bodysuit (eg Holland Cooper) so you keep the lux on top.
Make it more winter cosy with a shawl?

thanks - looking at Karen Millen now..
