How do I choose accessories?

I have bought my wedding dress and am now trying to figure out what jewellery and shoes to get. I am struggling! I basically never wear jewellery. I am finding lovely pieces on Etsy etc but am not able to picture them with the dress, particularly if the colour will work with it.

What would you choose? My dress is champagne coloured, A-line with deep V-neck, and the brand is White April Realm. I'll add a photo in the comments. Any ideas from some more stylish brides? :(
