I've had a few clients ask me on several occasions about the most suitable type of necklaces to wear with the various necklines. So today I am posting a cheat sheet (I can't remember where I originally found it) but it should definitely help you style savvy ladies with the right necklace to accent your neckline without competing with each other.
Rule of thumb
Turtleneck: Can be pretty much worn with just about anything; however go for chunky, bold and or long strings of beads or pendants
Crew/Round: Go for necklaces that follows the shape of the neckline such as bibs, collars or chokers.
Scoop: You can wear any length necklaces but looks great with pieces with volume.
Strapless: Go delicate and simple - single strand, choker, and short pieces that accentuate the collarbone.
Square: Some people say avoid angular pieces but believe angular pendants works well. Also go for chokers and or shorter round pieces.
Off the shoulders: This style is much like cowl necklines, however asymmetric pieces works well.
Halter: Slim pendants, single or multiple strands that rest above the cleavage works great for this style.
V-neck: Opt for Princess necklace with pendants, V-shaped pendants and beads that fall below the neckline.
Collar: short pendants and chokers makes for the best look.
Boat: This style enhances your neckline so keep it simple with long pieces.
Cowl/Plunging: This type of style makes a statement of its own, so just go for some statement earrings.
Sweetheart: Pieces that lie on the chest - chunky necklaces, pendant and chains.
Embellished (not shown): The embellishments are decorative enough so just go solo.
Now go out and dazzle them!
