Sarah, you have to have been a member for at least 10 days to add pictures directly.
Not too sure about whether it's too white or not; I am always bad at protocol. I think the stripes save it, but hopefully others will chime in on this.
I'm finding it very hard to answer your question, knowing nothing about you, where the wedding is taking place, and all the rest. Social context makes a huge difference: small town Arizona dresses very differently than NYC. I don't know what your age or style are, what you're aiming for. I could tell you how I would wear it, but would that be helpful?
It's a rather casual look for a wedding, IMO, so I would be aiming to dress it up. Chandelier earrings, well-styled hair, although simple. An intricate updo would be overkill. A blue floral pashmina or silk shawl would provide extra colour to move away from the white look and the extra layer for style and warmth, although a cotton georgette might be more appropriate with the fabric of the dress; hard to tell. Or a short open jacket in a colour that makes your heart sing. I had a great light pink one with silver threads in it that I bought for my son's wedding.
If you're adding colour to the outfit, add shoes that echo the colour. Pumps are a classic and go with almost anything, peep toes and sling backs are good options if the weather will be warm. Silver would be another option, or a colour that echoes your hair.
All of this depends, of course, on how they work together.
If you added a picture of you actually wearing the dress, and some indication of how casual or formal you want to go, I'm sure you'd get a lot more answers. As it is, it feels like shooting in the dark.
