A sapphire-blue cocktail dress is typically made of a rich fabric, such as silk, satin or chiffon, and could have sequins or other embellishments. Style this type of dress with metallic accessories -- the versatility of sapphire allows it to be paired with brushed gold, silver or gunmetal accessories. For example, a sapphire-blue silk halter dress is accented beautifully with strappy gold sandals, a gold cuff bracelet and dangling crystal and gold earrings. Carry a metallic minaudiere clutch to complete the elegant look. If your dress is sequined or beaded, stick with strappy heels or pointy-toe pumps in a metallic hue like silver. Wear simple button earrings -- think a matching metallic or sapphire-colored stone -- and finish the ensemble with a delicate silver bracelet.

Sapphire is striking when offset by black. Whether your dress is a sheath, wrap-style or A-line cut, black accessories instantly polish the look. Make your dress work-appropriate by adding opaque black hosiery and black pumps or kitten heels with simple silver jewelry. Top with a black blazer for even more professionalism. For a dinner date, pair a fitted, sapphire-blue scoop-neck dress with black slingback pumps and a matching black envelope clutch. Infuse glamour with a black enamel statement necklace and cocktail ring.

Take a light-hearted approach to accessorizing by incorporating color into your sapphire-blue look. A simple strapless piece is energized with the addition of a turquoise statement necklace, emerald chandelier earrings, a fuchsia clutch or an armful of colorful bangles. Orange and blue are complementary colors, so work in coral jewelry for extra visual impact. Balance the bright, statement-making hues with neutrals -- think strappy nude heels or pumps and basic gold hoops.

While evening dresses pair well with dressy metallics and statement-making jewelry, a casual sapphire sundress benefits from less formal accessories. Instead of sparkles and gems, add a colorful printed scarf to a simple spaghetti-strap dress. Or top a basic cotton frock with a cardigan in another shade of blue -- think cornflower, aqua or navy -- for a soft and pretty approach. Slip into nude, black or taupe ballet flats and add a matching skinny belt; carry an oversize neutral leather satchel to finish the ensemble.
