Weddingbee boards

First of all, here is my dress:

It has little pearl-like beads in the embroidered flowers, so I really want pearls. Here is the necklace I'm considering:

With either these:

or these:

And I really LOVE these, but I think they would be too much with that necklace:

The bonus is that the necklace and 2 of the 3 earrings (not the drop ones) are available through the animal rescue site. <3 My only concern is that the necklace may be a little overwhelming.

What does everyone think of the necklace, and which earrings???

Also, here are 2 of the earrings on a model (I HATE the necklace in the second pic though):

The dress is "diamond white" which is a very subtle ivory. (I didn't even realize it wasn't WHITE when I tried it on.) The necklace is white but one of the reviews said it picked up the ivory of an ivory wedding dress well. The pearls on the dress are VERY small. I don't expect to find a necklace that matches them perfectly and I think that'll still be ok.

If it clashes horribly, I can always return the necklace and start over. I just wanted everyone's opinion on the style of the necklace in general and whether that style would look good with the dress.

I'm wearing my hair in a french twist with flowers in it to match the flowers in my bouquet. I'm going for simple but elegant. I guess I should mention it's going to be a relatively informal outdoor wedding. (FI is wearing a black suit and dress shirt, no tie.)
