This mother-of-the-bride dress in eclipse blue chiffon is also ideal for the well-dressed mother of the groom or wedding guest. Three-quarter trumpet sleeves add a vintage vibe to the silky soft chiffon party dress, while a brightly-patterned display of rhinestones sparkles at the scoop neckline to diminish the need for jewelry. Fashioned in a relaxed sheath style, this jersey-lined beautiful blue MOB dress, under $100, is a sophisticated style choice for wedding celebrations, cocktail parties, and other semi-formal events.
