Probably the best starter clips are the tweezers style clips. they look like tweezers and have an adjusting band around them. Easy to adjust and can be set very light to wear as jewelry, or tightened up for fun. For long term wear, say clubbing, shopping, I would recommend nipple chains. The chains have loops on either end to hold your nipples. Not a bother for casual wear, but still good if you tug on the chain or hang a bit of weight from them. :-)
