I'm not a mom but am looking to buy cool gifts for my 16yo cousin (girl who goes to Holy Child) and 13yo cousin (boy at Landon). When I was at NCS (long time a go) there were certain items that were trends, and I know in the past few years there have been certain things that were "in" like Sillybandz (obviously totally 'out' now!!).
I've seen teen girls wearing these Lily & Laura bead bracelets:

I know guys are into things like Under Armour hoodies... What are the teen girl and teen guy trends I might not know about?
Sometimes there were even small things that became fads, like a particular type of pen (remember 'gel pens' anyone??), notebook, lipgloss, coin purse... or I remember a certain year those mid-calf socks came back for teen boys.
I'm not looking for general gift ideas here, but rather the specific fads that are in at the DC area prep schools.
