Available from Tiffany these are the higher budget option and are priced at £120 for both the charm and chain (watch out, the charm and chain are sold separately on line). However, if you are looking for something a little less expensive there are some really pretty alternatives available on Not On The High Street.
These Stirling silver initial necklaces are priced from £39 for one charm and the chain. There is an option to add additional charms too. Charms available include a diamante stone, a star (for all your wishes to come true), wings (to protect you and those you love), a butterfly (for freedom and belief in yourself), a heart (for love to be with you always) and a horseshoe (for luck to be with you always). So you can tailor your message/wish for each bridesmaid or even perhaps choose something in line with your Wedding theme.
