Where to buy a choker

[Greedyfly]

Hi, I have always liked chokers - but have yet to successfully find one that fits my requirements. I would like to buy one that is adjustable to neck size as they always seem to big/small. Preferably silver but am open to suggestions although NO gold hate it lol. I just want a funky, different, nice choker to wear when I go out. Any suggestions online would be great, shops too on the high street. I am allergic to costume jewelry so it has to be the good stuff. Thanks guys. I have no idea wheer to start looking online.

P.S: Or a necklace that would sit down the neck/cleavage that tightens around the neck, as though there is a hoop and the necklace goes through said hoop thats how it fastens - Similar to how people wear scarves. I apologise for my rubbish descriptions lol

Loads of shops sell them, I know I�ve seen some around but I�m not really a necklace person so don�t pay much attention.
Have to tried Muse of Accessorise and other shops like that?
