It's unusual to find skeleton bride costumes that aren't all white. This one comes with black gown, spiderweb tights, and black veil.
Your child can trick-or-treat dressed as a mini Bride of Frankenstein. Included are the dress, wig, and clompy shoe covers.
This Monster Bride costume for girls includes a black and green dress with beribboned top, petticoat, and hat. You'd have to buy the stitched gloves and stitched pantyhose elsewhere, and they do make the outfit extra cool. I don't think the boot covers are necessary - regular shoes would be ok for a bride theme.
This is my least favorite monster bride costume, as I think it looks more like an urban cowgirl. Your child would need a lot of personality to pull this one off. The costume includes the stitched hat and dress, but not the furry boot covers.
