Beautiful shades of purple highlight this year's collections of prom dress designs from Prom Headquarters. Choose a royal purple prom dress or a lovely lilac formal evening gown made by America's leading prom dress designers.

Purple is a symbol for royalty, personal strength and power. Lilac, a pale purple color celebrated in ancient Greek myths, has come to symbolize life, romance and abiding love. Our designer prom dress collection celebrates the passion of purple in exquisitely crafted evening gowns that highlight rich and pastel purple fabrics and accents.

We have enchanting designer lilac prom dresses by Ellie Wilde in embroidered tulle with sweetheart necklines, beaded bodices and flowing ball gown skirts. Our shimmery sheath silhouette prom gown with sexy V-neckline by Clarisse is available in a rich purple hue.

From prom dress designer Alyce Paris, our collection includes a floor-length purple prom dress fit for royalty. This fitted bodice dress with flirty sheer inserts has a design of gleaming chrome foil accents over deep purple.

A beaded scoop neckline adds a lovely look to our royal purple plus-size prom dress by Mac Duggal in a floor-length style with feminine lace-up back.

Find pastel lilac dresses with intricate lace embroidery and beautiful beadwork. We have short and long lengths in formal and semi-formal purple dresses. Brides who prefer bold over pale pinks outfit their bridesmaids in rich purple evening gowns from our designer formal dress collections.
