The 'Matinee' (60-61cm/24") also looks good with a wide array of outfits, including for business or casual wear. You'll find this length will work especially well over collared shirts and also higher necklines. If you are tall or have a larger neck try this length as your go-to size rather than the standard (princess) length.
All our necklaces come with a 45cm/18" chain.
