The easy way to imagine a wedding inspiration is to think "white." That's definitely valid, but a bit limiting. Try to consider shapes as well as color--the fitted bodice, especially strapless, is very popular right now. Look for ruching, interesting straps and details that might call to mind popular gown styles without taking it too literally. Any of these worn with black jeans would be adorable!
Alternately, go ahead and take it literally! A white dress can be a fun fashion statement. To keep it from looking too "bridal" (or really, too boring), pair it with some brighter jewelry and sassy shoes, maybe a brightly colored cardigan. Or, keep it simple and clean with a pair of pale flats and some pearls (or beads, for those of us who can't go out and pick up a string of pearls). I'm usually all about dark and rich colors, but there is definitely something enchanting about neat white lines. It makes me think of laundry; not in a "ugh, I have to do laundry" way, in a nice white clothes on a clothesline against a clear blue sky in a backyard in Sweden (or wherever air is fresh and cool and delicious).
You can also draw inspiration from the soft beauty makeup often favored by brides, and also put pretty things in your hair (flowers, bows, feathers, fascinators, maybe a tiny veil!). A little glamor never hurts and always helps!
