Tell me about your fashion sense

Okay Ladies I am a guy and as such need help in what charms to buy the ladies in my life. I have my Mother who is in her 70's I have two sisters in their 30's and Female friends all enjoy sterling silver charms. They wear them as necklaces and bracelets. So my question is what do I get them and what questions do I ask them so I do not get them the wrong charm? I like buying charms for my ladies. I like listening the stories behind all of them. Help me please.. I have found a site that contains silver charms to get ideas for me
